Dominic Mallary was a hardcore singer for the band Last Lights, and he twisted the microphone cord around his neck during every show. It’s a usually harmless trick frequented by industrial and hardcore acts, like Orgy’s Jay Gordon in so many videos.

Something went wrong on Thursday, and Mallary is dead. He didn’t accidentally hang himself or strangle himself. He just did his thing and finished his set at Boston University’s BU Central late night campus venue. It wasn’t until later that something was clearly wrong.

“He seemed fine for at least an hour or two, but after the last band played, he said he was feeling faint and couldn’t feel his legs,” Last Lights drummer Patrick Murphy told BU’s student newspaper, “The Daily Free Press.” “When they arrived at the hospital, he started to go into seizures, and that’s when he lost consciousness.”

He died a Friday at Boston Medical Center.

He was 24 and a 2007 writing, literature and publishing graduate of Emerson College.

“The Daily Free Press” reported that the band had been signed by the music label Think Fast! two days before the fatal show.

Boston University junior Jeanne Mansfield told the paper that Mallary sang well and seemed fine after the performance.

“He was amazing in what he was able to do, not even just in singing and screaming, but dancing and jumping around at the same time,” she told the “Free Press.” “It’s just weird to think that him doing what he apparently loved killed him.”
