Robert Powell investigates the rise and fall of Jazz Sabbath, a jazz trio from the late sixties, by interviewing bandleader Milton Keanes after the recent discovery of the lost tapes of their debut album. The album was initially canceled in 1970 when Milton was hospitalized just before its release. When Milton was finally released from hospital in September 1970, he found out that a band from Birmingham, conveniently called 'Black Sabbath', had since released two albums containing metal versions of what he claims were his songs.
