Herbie Hancock & Chick Corea in concert, "Button up", 1978

An Evening with Herbie Hancock & Chick Corea: In Concert is a live album recorded over the course of several live performances in February 1978 and released that same year as a double LP. The album features just Herbie Hancock and Chick Corea each playing acoustic piano. The use of only acoustic piano comes as a marked departure from both men's favoring of electric keyboards and a more jazz fusion style at the time.
