A compilation of non album tracks recorded in the late 60’s with his quintet of Herbie Hancock, Ron Carter, Tony Williams and Wayne Shorter. Don’t remember when or where I bought this but I don’t like it much. For one thing it is in bad shape with lots of crackles and pops and a few skips. About the only track I liked was the 18 minute “Two Faced: on side two from 1968 with electric piano by both Hancock and Chick Corea. This one will go in the trash.
