The Rock Band library of downloadable content expands next week with tracks from California rock group The Offspring, Grammy Award winning alternative quartet R.E.M., and Richard Thompson, who is according to Rolling Stone one of the top twenty guitarists of all time.

Harmonix has done a wonderful job keeping their game fresh.  Every week a new hope is born that maybe, just maybe your favorite group or song will make the cut.  This week’s all mastered recording DLC includes:

• The Offspring- “All I Want”
• The Offspring- “The Kids Aren’t Alright”
• R.E.M.- “Losing My Religion”
• Richard Thompson- “The Way That It Shows”

The tracks will be available for individual download Tuesday for Xbox 360 and Thursday for PS3, priced at the normative 160 MS points and $1.99 respectively.
