 Co-founder Ignorant has cited The Clash and David Bowie as major personal influences.Band members have also cited influences ranging from existentialism and Zen to situationism, the poetry of Baudelaire, British working class 'kitchen sink' literature and films such as "Kes" and the films of Anthony McCall (McCall's "Four Projected Movements" was shown as part of an early Crass performance).Crass have said that their musical influences were seldom drawn from rock, but more from classical music (particularly Benjamin Britten, on whose work, Rimbaud states, some of Crass' riffs are based), free jazz, European atonality and avant-garde composers such as John Cage and Karlheinz Stockhausen.
