In 1977, Penny Rimbaud co-founded seminal anarchist punk band Crass.

In 2003, he founded what was at first known as 'The Crass Collective', then 'The Crass Agenda', then 'The Last Amendment’ and finally 'L’Académie des Vanités' – a collective of jazz musicians, artists and filmmakers who shared Rimbaud's lifelong interest in progressive, improvisational art. less
