Chick Corea, bassist Miroslav Vitous and drummer Roy Haynes made the classic Now He Sings, Now He Sobs in 1967. Fourteen years later, they met again to record the award-winning Trio Music, a double album consisting of one disc of free improvisations and a companion disc of seven tunes by Thelonious Monk. Mercurial and constantly inventive, the playing is top class throughout. The free stuff has something of Messiaen’s bird music about it, while the Monk set is puckishly brilliant. The original double album is here repackaged as a single disc.
