At 10 minutes to show time, almost every band on the bill was present and accounted for. The doorman was still missing, but he was probably just running late. Outside, a patch of lousy smarch weather dampened the dirty sidewalk.

The circumstances at O’Brien’s Pub last weekend, through no fault of the venue, were not exactly conducive to a rowdy rock and roll show. It was Sunday, too, and barely the afternoon. Allston seemed busy nursing its hangover.

The crowd inside could accurately be called a crowd: 40 or so people, more than half of O’Brien’s room capacity. They were well into their first Sunday beers. No coffee or brunch on this menu. The video golf machine in the corner? Dead, unplugged. Al the sound guy had the Descendents on the PA. He untangled cables and tried to reach the doorman on his cell phone. There was change to make, and a lot of hands to mark. No answer.

Enter Ryan Agate. Oh, he’ll take the door for now, no problem. After all, Ryan The Terrible—as he’s known on flyers—booked this show, the fourth in a weekly series of Sunday matinees that he’s aptly named “Day-Drunk Pop-Punk”.

“This [series] has been surprisingly successful,” he says, sipping a Miller High Life kept cool by a koozie brought from home. “We usually get 30 or 40 people. It helps I made a catchy name.”

Along with his ability to alliterate, um, alluringly, Agate is a rock promoter who can juggle the duties of talent buyer, graphic designer, band mother, ringleader, heckler, and, yes, even doorman. He’s almost too cheery to be drinking this early. His upbeat attitude can seem a little at odds with that of the “older, jaded punk rock bands” he tends to support, but someone has to keep the show on schedule – even if its theme is three-chord tunes and, well, drinking early.

Agate is only one of many Boston promoters trying to do one thing: set up the kinds of shows they wish they could attend. It’s not always easy, especially for younger bands who try to do it themselves. The city has a reputation for being an absolute haven for new music, and boy, is it ever. Yet very few Boston-bred artists get more than a dollop of national attention before they fizzle out, or relocate to New York to fizzle out.

Chalk it up to a problem of logistics. That’s where promoters come in. Will Mayo, who organizes noise, psych, and other self-proclaimed “weird” shows, understands that the prime directive of any artist is to find a place to showcase their work.

“The hardest part [about Boston] is the lack of venues and the city’s lack of support for the non-commercial elements of the art and music scenes” Mayo says. “That issue is compounded by the fact that people tend to leave Boston shortly after they’re done with school.”

Those very kids make up much of the target demographic for small club shows, and so they remain small, as if by design. This is far from a destructive force, but it does have a crowding effect. In a city full of smart, creative folks, there is an awful lot of good music to take in, on a variety of scales. It can be daunting to a fan and unforgiving to an artist.

A vast network of bands, movements, scenes, collectives, venues, clubs, and promoters all compete for attention. And they change rapidly about every four years. The hyper-specificity of Agate’s Sunday shows isn’t just a cute gimmick; it’s a rallying cry to the music’s base.

“One of the things that I try to do is to be the voice for those smaller bands,” Agate says. “Get them into a real venue so they can play for people they wouldn’t normally play for. And it’s worked out really well for some of those bands.”

Boston has a wealth of those “smaller bands,” and they find places to play even if the corporate-owned venues on Lansdowne Street aren’t offering opener slots (national booking agents generally pick those). Throughout the week, dozens of houses and basements around town operate under the radar.

Spaces like the Democracy Center and Lorem Ipsum Books also open their doors for all-ages shows. Neighborhood bars like P.A.’s Lounge and the Midway Cafe give way to mid-sized clubs like the Middle East and Great Scott.Agate and Mayo have booked pretty much all of them at one time or another, and they’ve been at it for nearly a decade, first in service to artists they like.

A principled approach like this begs for red tape. Most music venues, even non-profit spaces and event halls, require room costs. Some bars will have to make a certain amount of money in drink sales before the bands can see any of it. Most promoters are no strangers to having to pay their bands out of pocket at times. The age restrictions at bars pose an even weightier issue: why book a band at a place many of its fans aren’t allowed to enter?

The Democracy Center in Harvard Square solves this problem with three rules: shows must admit all ages, be booze-free, and end by 11. Kimberly Jane, who works part-time at the non-profit, also books hardcore shows in its ballroom. They’ve caused a few broken windows here and there, but have done well enough lately for Jane to start a fund for such incidental repairs.

“It’s really important to me that everybody who wants to see a show can,” she says. “When people are shut out because of age, it’s very clearly a nod to alcohol sales. I go to shows because I want to hear the music. If you want to drink, there are bars around, and there’s a river you can walk to and drink at. Just because a space is alcohol-free doesn’t mean you shouldn’t go to shows there.”

The Democracy Center challenges more than a lack of all-ages shows. The venue hosted part of last weekend’s Smash It Dead Fest, a three-day event featuring more than 25 bands benefiting the Boston Area Rape Crisis Center. Jane was part of a collective that raised more than $4,000 for the center.

But big charitable festivals simply can’t happen every weekend. Smash It Dead required months of planning, and went smoothly thanks to lessons learned from the previous year’s effort, when a slew of last-minute venue changes nearly derailed the event.

Agate has had some time to learn tricks of the trade, too, if on a smaller scale: work with people and places you like, book shows in all sorts of spaces, see what works for what kind of gig, avoid shows in January.

He says the hardest part about booking shows in Boston is trying to make the bands happy. He’s a guy who knows his audience because he is his audience, often no more or less than a friend of the band. For his purposes, all-ages shows aren’t a necessity.

“Of course there are disadvantages to doing shows in bars,” Agate says. “Certain people won’t attend age-restricted shows, even if they’re of age, on principle, and that’s a valid point. But it makes my job easy to have a sound guy and a bartender at a place like O’Brien’s. If I can make 10 people come through the door, I can pay the bands.”

Three blocks from O’Brien’s, though, starts a spread of lofts and basements that take care of their bands in a different way: they’re usually absolutely bonkers. “I mainly appreciate working with bars for the simple fact that they’re reliable,” admits Will Mayo. “Of course, the wild energy of the basement is hard to capture elsewhere.”

One such Allston space sprouted up last year thanks to the efforts of Nate Richardson and Ben Henry. They’re nothing more than two brazen knuckleheads who “sling food poorly” for work and strive to put on good shows for their friends’ bands. Though they admit to “stealing the business model” from Somerville’s famed studio/space Starlab, “they’re way better than us,” says Henry. “They drink less during shows, book better shows, and are much nicer guys.”

“Yeah,” says Richardson. “They probably use a calendar.”

These two dudes pay for their room themselves, though. Even if the show doesn’t go so well (i.e.: graffiti, fireworks, windows kicked out, people thrown down stairs), the band on tour is usually compensated, and the local acts will get to play for their friends and maybe make some new ones.

“You can’t always get the band more money at a bar,” says Richardson. “Sometimes you can’t get the band any money. A bar is going to be pretty strict on their room cost. We try to be strict on ours, but if the band’s not getting paid, we’d rather pay the band than take the room fee.”

Richardson’s option to forgo his own room fee is not one afforded to legitimate venues. Unlisted, donation-driven shows, where the floor is as shaky as the legality, are asking to be shut down. For all the righteousness, a nagging struggle over money remains. Touring bands are likely to be assertive about how the money at a gig gets handled. Booking agents are more likely to make unreasonable demands far before the date is ever set. Both The Terrible Agate and the Democracy Center’s Jane admit to simply crossing off much of a band’s tour rider. It’s never out of spite – again, it’s a problem of logistics.

“Apparently there’s a lot of money in show-booking that I don’t know about,” says Agate, who prefers to pay out with a divided percentage of the door. “I know what the bands make. I know what the shows make. I don’t make anything. A lot of bands and venues don’t make anything. Where’s the money in this? A lot of people wrongfully assume that bars are making hundreds of thousands of dollars. A perfect example is a Monday night at Charlie’s [Kitchen in Cambridge]: if we make 300 bucks at the bar we’re doing all right.”

For the moment at least, so is Boston’s music scene. Its promoters are its unsung heroes, sacrificing time, money and windows. Bands and venues will come and go. Trends will sparkle and fade. Students will graduate and move back home. Yet against all odds, there’s still always something going on, if you know where to look.

“Special” Ed Oliveira lounged on the sunny outdoor deck out back at Allston’s Deep Ellum, nursing what can’t possibly be his first Allagash of the day. He’s all smiles and small-talk with a pair of female brunchers at a nearby table, letting his aviator sunglasses draw just enough attention away from the faux-hawk he sports with mock seriousness. The girls thanked him for his menu recommendation and giggled at his inaudible closing quip before he refocused his attention.

Listeners?

“Fans,” Oliveira clarified. “Let’s call them fans.”

It was just after noon on what seemed like hottest Saturday of the year, and one thing was already certain: The guy knows how to knock back a cold one long before it turns warm. He also knows his strengths as a radio personality. Words roll off his tongue as if he had a six-figure audience there to hold onto each one. He’s not fishing for laughs, but he is listening to himself.

If I ran golf, it would be a full-contact sport, said Special Ed (Blast staff photo/Sarah Gordon)

“The Washington Redskins and the New England Patriots are complete cosmic opposites,” Oliveira mused at one point, invisible fists raised in anguish to the football gods. Other deep thoughts: “Satellite radio is already dead,” and “mixed martial arts is the pinnacle of full-contact spectator sports.”

He gets even better later on: “If I ran golf, it would be a full-contact sport. All players would carry a quiver of the four basic clubs and travel on foot. It would be survivalist golf. There would be no waiting. An opponent can sneak up behind you while you’re putting and break your legs with his driver, and you’d lose.”

Fine craft brews aside, this is more professionalism than narcissism. And it helps that Special Ed is actually quick and funny. He verbalizes thoughts, tries out material, comes back to talking points for another go-round. At least the cute waitress in the sundress and the menu-challenged ladies to his left are within earshot. They’re getting a free show, and they don’t even know it.

Consider this rehearsal, then. For the past two years, Ed has acted as one-third of The Sandbox, WFNX’s uncharacteristic attempt at a talk-centric morning radio show in the Boston market. The move was met with some criticism. How can the historically musical FNX justify a four-hour broadcast with maybe a dozen rock songs thrown in to break up the banter? This is the station that broke The Pixies. Kurt Cobain was an avid listener. You know, “Boston’s True Alternative?” As it is, this clogged market is rampant with humor-and-talk teams: Toucher and Rich on WBCN, Ramir and Pebbles on JAM’N 94.5, Opie and Anthony on Sirius/XM, Howard Stern, etc. With such immense pressure and competition, it’s easy to see why Oliveira never actually drops the routine. In truth, there isn’t one.

“I can’t turn it off,” he said. “I’m not playing a character at all. The Special Ed you hear on the radio is 100 percent genuine. Off the air, I’m still that same asshole.”

That’s hardly an understatement, though one would be tempted to apply “lovable” as a modifier for that self-given title. “Fearless,” too. For what other New England semi-celebrity would call the sport of baseball “boring and outdated” and riff on his “newly instilled sense of annoyance for the Boston Red Sox” that comes along every summer? Oliveira has lived in Boston only a little more than two years, but this apparent cultural divide illuminates his overall appeal. Like much of The Sandbox’s young-and-hip listenership, Oliveira admitted Boston may not be his permanent home, but in the meantime, he hates the Green Line for the same reasons as the rest of us and is no stranger to the phrase “Boozy Mick.” The only difference is that it’s part of his job to talk about it.

“I don’t find many of the aspects of Boston pride all that sacred,” Oliveira said. “I think we aim to attract an overall intelligent audience — a more worldly audience than just Boston. It’s a great market and a great town, and FNX is a great station. But our industry’s so weird right now that it’s hard to tell where it’s going. If you wanna be a movie star, you go to L.A. If you wanna be a radio guy, you go where the work is.”

This is exactly what he did in the summer of 2007. Along with co-hosts Charlie Padgett and Dustin “Fletcher” Matthews, Oliveira was transplanted from WYDL in Richmond, Virginia to take over Michael Swayze’s popular morning rock show on FNX. Since the transition, music for the time-slot has been cut down to “maybe four songs an hour,” while a wide array of topics are discussed each day in a rapid-fire call-in format: News, sports, politics, movies, music or “basically whatever we feel like,” Matthews said.

Among the trio’s talk are special guests, interviews, comic bits and commercials. The latter is probably the most significant change from the show’s birth as a podcast in Virginia, besides then being able to swear. Oliveira (whose real last name is d’Oliveira), Matthews and Padgett worked at WYDL doing marketing, afternoons and mornings respectively. They started The Sandbox as a podcast in 2004.

“We were never live before FNX,” Oliveira said. “The original idea was just to have an excuse to goof off, swear and drink. But people listened. We were in three different states at one point, and thanks to Skype, we were still able to record the show together, as if we were all in the same room.”

The three low-on-the-totem-pole radio employees would not have had the chance to do a podcast at all had it not been for WYDL higher-up Mike Murphy. “Mike was the buffer between the people behind the boardroom doors and our shenanigans,” Matthews said. “He made it possible for our podcast to exist.”

Despite the blessing from Murphy, Matthews (who is Ed’s roommate) maintains that “the funniest stuff happened off-air, like when we built a bathroom in Mike’s office.” The team installed restroom amenities like a toilet and a faucet, not to mention a fully operational plumbing system, in a room that was big enough for only Murphy’s desk and bookshelf. Murphy was simultaneously confused and amused. While not a gag that would work well on radio, one has to admire the anarchic inventiveness.

The youngest host of the show, Fletcher Matthews stuck to bottles of Miller High Life, sporting plastic lime-green wayfarer knockoffs to rival the kitschy impact of Special Ed’s aviators. The conversation veered off to the recent Best Music Poll free concert, to the The Gaslight Anthem, to the gruff Midwest punk bands that somehow instantly unite their common listeners. The back deck of Deep Ellum was once again bathed in sunlight and populated by groups of attractive drinkers soaking in the vitamin D as their livers do the alcohol. There was not a microphone in sight but Oliveira and Matthews appear in their element. A surprising amount of their rapport later winds up as asides on the following day’s show. The waitress — same as before — brings over each new longneck as the previous one’s frothy final gulp is about to be consumed.

Clearly comfortable with each other, the Sandbox guys know how to make an impression. But they weren’t so lucky upon their initial meetings with WFNX as the station searched for a possible new morning show.

“It was a long, slow hiring process,” Oliveira said. “But the beautiful thing about FNX is that they don’t think just like a radio company.”

Matthews chimes in: “They are very protective of their workplace and the people are passionate about what they’re doing. They have a huge standard for quality and a demanding audience to maintain. You know the FNX audience is tough to impress. It’s like, ‘Oooo … we all love Roxy Music.’”

Challenges presented themselves early for the trio. At one grueling interview in Boston, the General Manager was an hour-and-a-half late. “He barges in the board room,” Oliveira said, “and says verbatim to us, ‘Sorry I’m late but I don’t give a shit about any of this.”

According to Fletcher and Ed, even Henry Santoro, a radio veteran and longtime WFNX stalwart, was initially unimpressed. “I’m not kidding,” Oliveira said, “but he said he wasn’t interested in any of our ‘small-market bullshit.’ Unless we made some changes.”

That request was honored, and Matthews, Oliveira and Padgett got the job. They broadcast the first Sandbox show on July 23, 2007. The initial response from the public was overwhelmingly negative, as is the norm for regular radio listeners to throw their arms up in defiance at the first sign of change. Fast forward two years and Santoro is now a regular on the show. “They told us, ‘Oh, and you also get Henry. He just sort of comes with the station,’” Oliveira said. “Despite the fact that he’s sort of just a piece of furniture that hangs out in the studio, he eventually became a father figure for us on the show.”

Co-host Charlie Padgett confirmed Santoro’s status. “The only thing that makes Santoro “Ëœlegendary,’” he said, “is the fact that he has managed to hold down the same job for 26 years by doing the absolute minimum amount of work possible.”

Padgett is a little older than Matthews, a little younger than Oliveira, and is referred to as the “vanilla” one by his colleagues. Case in point, he was absent from the afternoon bar trip because he was taking his wife and kid fishing. But he defines his role in the group a little differently. “Just because I don’t live in an apartment with outdoor-carpeting indoors doesn’t mean I’m “Ëœvanilla,’ he says. “I got my rock n’ roll lifestyle out of my system 10 years ago, when I was single, sort of good-looking and in halfway decent shape.”

If anything, Charlie rounds out the ball-busting dynamic that has helped The Sandbox quickly establish a loyal audience. There’s a certain affection to the extended arguments on the show that shows up in conversation. “Ask Ed,” Padgett said, “who’s 38 by the way, how many times he has been asleep in the floor of the green room on a Tuesday morning compared to how many times I have been asleep in the floor of the green room. And no one can be as hipster-awesome as Fletcher. “ËœOoooooh! I only go to bars that take cash!’ Get out of here. Give me a corner booth, a decent-looking waitress and a few hours and I’ll show you a good time.”

Or just hand the man a microphone.

Now, distinguished guests like Loveline’s Dr. Drew and the comedian Gary Gulman champion their experiences as some of their favorites. Oliveira is particular taken by Dr. Drew. “If it were up to me,” he says, “I would replace Charlie with Dr. Drew any day.”

Still, the rag-tag dynamic and speed of high-energy talk radio remains, The Sandbox having come into its own recently pretty much by just being itself. “It comes down to this,” Matthews said. “There’s no sleeping in. We have a show to do. But there’s a constant dog pile mentality. If there’s any sign of weakness on-air, you jump on it until it’s crushed.”

“We are all such sensitive babies who constantly criticize our own work,” Oliveira added. “A normal person would be reduced to tears.”

The guys insist that whatever they have to offer is either self-taught or at least affectionately derivative. These guys were raised on Howard Stern, whom they idolize, but The Sandbox possesses an attitude all its own. The hosts are engaged in a “love fest” with Sam Yoon that involves the ringing of a gong each time the candidate is on air. They think it would be funny to do a segment called “We Need More Black Friends.” They had Fletcher do a serious review of the animated 80s version of Transformers: The Movie, where their “Bah Weep” slogan originated. See? It’s natural.

“I went to the University of Tennessee for like a weekend,” Matthews siad. “It was pointless. There’s no guarantee to be successful on the radio and you can’t just learn it at some media studies program. Are you a hard worker that’s good on the air? Then you’ll be successful. That’s it.”

It also helps if you can put away a dozen beers before 3 p.m. and still be able to shoot the shit on a summer’s day. As if it were your job or something.
