They're back, sort of. Black Flag takes the stage on Thurs., Sept. 5, on the group's first official tour after calling it quits in 1986. Since entering the punk canon with 1978's landmark Nervous Breakdown EP, Black Flag tore up the West Coast with its trademark atonal riffs, cathartic bellowing, and jolting tempo switches. With two disputing versions of the immortal hardcore band on the road this year (awkward copyright battles included), this incarnation features one of the group's two founding members, guitarist Greg Ginn, along with vocalist Ron Reyes, aka Chavo Pederast. Screeching Weasel bassist Dave Klein and drummer Gregory AMoore fill out the lineup. It’s difficult to say if Ginn’s version of Black Flag will stay true to its legendary intensity, but here’s a chance to experience some killer classic punk songs.
