While some British punk bands blustered and bellowed showily in attempting to adopt a radical image, there was never anything inauthentic about Stiff Little Fingers. The fiery group were formed in Belfast, Northern Ireland, in 1977 in the midst of the Troubles, and singer-guitarist Jake Burns found plenty of lyrical inspiration just outside his front door in the violent streets of his divided hometown. Such explosive tracks as “Tin Soldiers” and “Suspect Device” still sound powerful today, although Burns and bassist Ali McMordie are the only remaining members of the band’s early lineup. They’re well matched with The Avengers, the confrontational San Francisco band who combine proto–riot grrrl Penelope Houston’s yearning, searing vocals with Greg Ingraham’s relentless guitar on riotous original anthems “We Are the One” and “The American in Me” and a savage evisceration of The Stones’ “Paint It Black.”
