It’s a practical problem any band faces upon breaking up: Who, if anyone, will retain the rights to use the band’s name and perform its songs? But when your band is also an amorphous anarchist collective, it becomes an even more fraught philosophical issue. Can any autonomous individual lay claim to the Crass brand? Do you have to call a house meeting and decide by consensus? And for Bakunin’s sake WHO WILL TAKE OUT THE TRASH?! For whatever it’s worth, Steve Ignorant’s recent performances of Crass’ songs has the grudging approval of co-founder Penny Rimbaud (“I acknowledge Steve’s right to do this,” Rimbaud told the Guardian in 2007, “but I do consider it a betrayal of the Crass ethos”). What’s undeniable is that Crass’ original 1977-1984 run of music, art, and activism made them indelible anarcho-punk icons—and whether you let nostalgia get the better of high crusty ideals is your problem. Preceding the show (from 6-7:30pm), local writer Chris Estey will conduct an interview with Ignorant at the Comet Tavern. With Goldblade, The Estranged. ERIC GRANDY
