Rosenbombs is a raw, fast and pissed off powerviolence assault from the Bay Area, made up of members from Doppelganger and Punch. If you're a fan of their other projects, I wouldn't hesitate on snagging these tracks. Everything I could find is posted below. Enjoy, these guys were rowdy-as-hell! DIG!!!
