Jas Heriot Duke (1939–1992) was a cult figure in the Australian performance poetry scene.
He writes "I started performing poems as a timid person with a stutter but the spirit of the times soon converted me into a bellowing bull."
During the 1960s he travelled to the UK and Europe and participated in the underground publishing and filmmaking scenes in Brighton and London.
Returning to Australia in 1972 he worked as a draughtsman and continued publishing and performing, writing a novel about his travels entitled Destiny Wood.
[1] Duke's writings included translations of French and Eastern European Modernist poets but he is best remembered for his sound poems.
