Along with Rollins, Thelonius, Trane, Miles, Blakey, Carter, and most indubitably Mingus, one of the best jazz artists that encapsulated life in their music.
This song has kind of a Motown/HDH sound at the beginning,, withe the harpsichord intro--kind of like what was done with The Four Tops at that time.
this song first titled "For Carlos" was written by Herb Alpert and his TJB, found on their SRO album, 1966 release.
