Recorded mostly in the early'60s with Ra, Marshall Allen, John Gilmore, James Jacson, Nimrod Hunt and Thea Barbara, Space Probe explores stripped back forms and colour combinations that are far from jazz Ð or that attempt, very successfully, to take jazz into wholly new territories. Especially notable is the extraordinary Conversation Of J.P. for piano and percussion which, along with the opening track - an 18-minute Moog solo, probably recorded in 1970, just after Ra had newly acquired the instrument and was still putting it through its paces - make this an essential release in the Ra canon"-Art Yard
