The most important jazz pianist playing today, in his Standards Trio format (less indulgent than some of his many solo recordings), but with the humming, the eccentric vocalizing, and the odd posturing & body language that are part of his intense involvement with the music. Having seen him live many times, all this doesn't bother me. But there are some--including several jazz critics--who are distracted and irritated by it. If curious about his work, a new listener might be better off just buying a CD or downloading one of his Standards Trio releases and listening to his music.
Having said this, his playing is astonishing--he is a genius, if a difficult one--and his uncanny interplay with Peacock on bass and DeJonette on drums borders on the psychic. Having played together for so many years, and all three being great jazz musicians in their prime, it's not a mystery. It's deeply satisfying to both hear and SEE the pleasure they take in their improvised conversations--an extra element that only comes through on video.
Note: to fully appreciate the music, you've got to go beyond TV speakers. This DVD deserves a good high-end sound system. The video quality is fine, but as another reviewer pointed out, the mike placement and overall recording is terrific. As you would expect with anything that ECM puts its stamp on.
