Last Thursday the one and only Ahmad Jamal played Davies Symphony Hall as part of SF Jazz. Long acknowledged by Miles Davis as a major influence, he is one of the most influential musicians in the history of the music. His sense of space and touch and dynamics are breath-taking. And his long montunos, often at the begining and end of tunes, I believe forshadows modal jazz. With Herlin Riley on drums, Reginald Veal on bass, and former Weather Report percussionist Manolo Badrena, the quartet achieves a telepathic level of rapport. Invitation and Blue Moon were wonderfully re-worked, as was In Your Own Sweet Way, perhaps a nod to the Bay Area's own Dave Brubeck. Almost all improvising musicians are adept at covering mistakes, or turning them into happy accidents. With Ahmad there is no need - even at the age of 82, every note, every phrase, is perfect. He walked out on stage to a standing ovation, and received several more for each encore. The last piece, of course, being Poinciana. Still fresh, still inspiring, still mysterious.
