The On the Corner stuff is great. It includes the segment used by Bill Laswell for “What If” on Panthalassa.
“Chieftain,” as I mentioned before, is the same tune that opens In Concert at Philharmonic Hall.
The “Turnaround” tracks are the same tune from the second part of “Prelude” on Agharta. Some of this music was used on Panthalassa.
“The Hen,” “Big Fun-Hollwuud,” and “Peace” are kind of dull along the “Billy Preston” lines and lack the edge the band had in its live shows.
“Mr. Foster,” recorded the day after “Calypso Frelimo” in 1973, is a good one. It sounds like “For Dave,” which closes Agharta and Pangaea and is on the latter part of Side 2 of Dark Magus. Confusingly, the more mainstream “Minnie” from 1975 is also known as “Mr. Foster.”
“Hip Skip” and “What They Do” are from 1974 and include Dominique Gaumont on guitar. The former song features Pete Cosey on drums and was performed on a few live bootlegs from this period; the latter is a great stop-start guitar-fueled rave-up not unlike the “Turnaroundphrase” finale on Dark Magus.
