Recorded live at the Ann Arbor Blues & Jazz Festival, September 1973.
"Sun Ra's 1973 appearance was even more highly anticipated than ever before. The Arkestra was at the peak of its powers, with an array of brilliant soloists like John Gilmore, Marshall Allen, Eloe Omoe, Ank Tal Ebah, and Kwame Hadi continually swirling forth from Ra's inexhaustable font of music and color, fired by three sets of drums and equal number of hand percussionists and topped by Sun Ra's inter-galactic keyboards and the space voice and interpretive dancing of the magnificent June Tyson." -- from the sleeve notes by John Sinclair

After the City Council had forbidden the annual Blues & Jazz festival to take place in Ann Arbor, the organisers, Rainbow Multi-Media, found an alternative venue in Windsor, Canada. But with Creative Director John Sinclair deported back to Detroit and the audience harassed by the Canadian police, only a small crowd saw and heard Sun Ra perform with his Intergalactic Arkestra, whose "ranks included Ra's greatest reed section ever, with Marshall Allen, John Gilmore, Elo Omoe, Danny Davis, James Jacson and Danny "Pekoe" Thompson, plus Kwame Hadi and Akh Tel Ebah on trumpets". -- from the sleeve notes by John Sinclair

Recorded live at the first Ann Arbor Blues & jazz Festival, September 1972. With first public performance of 'Space is the Place'.
"The best of the Arkestra's performances during this period unfolded into one continuous multi-media exposition of the music and space philosophy of its leader, moving seamlessly from beginning to end under Ra's direction to create a splendorous tapestry of sound and sight, the likes of which had never been seen or heard before". -- from the sleeve notes by John Sinclair
