When this album was released in 1975 by Paul Bley's Improvising Artists label, the seven selections had been previously unheard. The five pieces from Mar. 9, 1964 (which feature pianist Bley, tenor-saxophonist John Gilmore, bassist Gary Peacock and drummer Paul Motian) were later released in a more complete form on the Savoy LP Turns. This was a unique onetime encounter between the innovative Bley (whose lyrical approach to free form improvising was quite different than that used by the high-energy players of the time) and Sun Ra's longtime tenor John Gilmore; "Ida Lupino" is the most memorable of these tracks. In addition there are a couple of trio performances ("Mr. Joy" and "Kid Dynamite") from a May 10, 1964 concert with bassist Peacock and drummer Billy Elgart that have not been released elsewhere. Very interesting if not quite essential music.
