If you can, pick up Mwandishi: The Complete Warner Brothers Recordings. It includes this whole album, as well as Crossings (which is my favorite stuff on the album) and Mwandishi. I’ve been listening to this album regularly for the last several decades, and it NEVER gets old.
Edit: looks like there’s an even more complete compilation from this period now: The Warner Bros. Years 1969-1972. I’m off order it momentarily…
