Sam Rivers is the man.
This is his second solo album, recorded in '65 right after he left the Miles Davis Quintet (he appears on only one Quintet record, Miles In Tokyo). It wasn't that Rivers wasn't up to snuff with Davis, it was that he was too "free" to play Miles' compositions the way they were intended- that and; frankly, he was too good to be a sideman any longer. Take this record by itself (or as a companion piece to Fuchsia Swing Song, also released in 1965) and you have some of the finest avant-garde post bop of the mid-60s.
The line-up here is spectacular as well, Freddie Hubbard (trumpet), Herbie Hancock (piano), Ron Carter (bass) and Joe Chambers (drums).
