We all love Chick Corea. The man played on some of Miles Davis' best albums and in the process gave us the face melting Rhodes solo on "Miles Runs the Voodoo Down". For that alone we should all be grateful. Before going on to play fusion with Return to Forever he also gave us this obscure atonal masterpiece. Accompanied by Miles collaborator Dave Holland, Barry Altschul, and a relatively unknown at the time Anthony Braxton, Corea pays tribute to modern composers like John Cage with free improvs that turn into spastic freakouts. True avant garde shit. Few people can make a piano sound like the sky is falling. Corea does it with ease.
