Penny Lapsang Rimbaud (born Jeremy John Ratter, 1943) is a writer, poet, philosopher, painter, musician and activist. He was a member of the performance art groups EXIT and Ceres Confusion, and in 1972 was co-founder of the Stonehenge Free Festival, together with Phil Russell aka Wally Hope. In 1977 with Steve Ignorant, he co-founded the seminal anarchist punk band Crass and served as its drummer. Crass disbanded in 1984. Until 2000 Rimbaud devoted himself almost entirely to writing, returning to the public platform in 2001 as a performance poet working with Australian saxophonist Louise Elliott and a wide variety of jazz musicians under the umbrella of Last Amendment.
