Free Jazz Communism is a new book actualising Archie Shepp–Bill Dixon Quartet at the 8th World Festival of Youth and Students in Helsinki 1962. Including archive material and documents, commissioned theoretical and historical texts, and interviews, the book edited by Sezgin Boynik and Taneli Viitahuhta contextualizes politics of free jazz music in light of global decolonisation movements, anti-war activism, structures of racial capitalism, and forms of avant-garde music.
