In addition to the standard two-channel
stereo album there was also a four-channel
quadraphonic version released in 1973 on
LP and
8-track tape. The quad LP was encoded in the
SQ matrix format. The first CD issue was in 1986. A
remastered version of the album was released on CD in 2000 by
Sony Music Entertainment. It features a new set of
liner notes by
JazzTimes critic Bill Milkowski, as well as photographs of the band. In 2015 the album was re-issued on
Super Audio CD by Audio Fidelity containing both the stereo and quad mixes. The same content was re-issued on SACD in Japan in 2021 by Sony Music. The track "Celestial Terrestrial Commuters" appears on the six-CD box set
