At least one of the participants here, pianist Chick Corea, is an old hand at great duets. He has performed and recorded with Herbie Hancock, Ralph Towner, and Gary Burton. Here, his partner is the Japanese pianist Hiromi, and the sparks quietly fly and flare throughout. Corea has long been one of jazz’s most lyrical pianists, and his influence is obvious on the younger Hiromi. Her style, however, is a bit punchier, and more rhythmic--this makes for fine contrast between the two. On this double-disc live opus, the pair offset each other beautifully, engaging in give-and-take on originals (by each) and choice covers (the Beatles’ “Fool On The Hill”).
