CoreaHancock
CoreaHancock is an acoustic live album by Chick Corea and Herbie Hancock. It was recorded over the course of several live performances in February 1978 and released in 1979. Corea has first billing on this album, as Hancock was credited for An Evening with Herbie Hancock & Chick Corea: In Concert, another recording of the same concert tour released by Hancock's label. The CD version heavily edits the final side of the vinyl release. Unlike An Evening, CoreaHancock has not been reissued in an unedited format. As of 2015, the album has been reissued unedited in digital format on HDTracks.
Hancock makes reference to Corea's albums Piano Improvisations Vol. 1 and Vol. 2 in his introduction of Corea on this album.
