Peter Brötzmann was a German jazz saxophonist and clarinetist regarded as a central and pioneering figure in European free jazz. Throughout his career, he released over fifty albums as a bandleader. Amongst his many collaborators were key figures in free jazz, including Derek Bailey, Anthony Braxton and Cecil Taylor, as well as experimental musicians such as Keiji Haino and Charles Hayward. His 1968 Machine Gun became "one of the landmark albums of 20th-century free jazz".
