Fronted by the controversial Egor Letov, Siberia's Grazhdanskaya Oborona (Civil Defence) were major catalysts for the Soviet punk revolution. The band's music and lyrics oscillated between anti-authoritarian performance art and crude rock poetry. Propelled by Letov's raspy, visceral cries, their sound was both philosophical and politically provocative—a bricolage of urgent and slow-burning punk, raw garage, industrial noise, lo-fi and psychedelia. Their extensive output began in 1985 and ran all the way to 2007, via Letov's psychedelic adventures with Egor i Opizdenevshie in the ‘90s.
