SF Jazz this week was quartet heaven. The Spring Quartet on Wednesday featured Joe Lovano (sax), Leo Genovese (piano), Esperanza Spalding (bass), Jack DeJohnette (drums). They were all excellent, played well together, and were very entertaining. But then Saturday was the Superstar Quartet with David Sanborn (sax), Joey DeFrancesco (B3 organ), Billy Hart (drums), and Bobby Hutcherson (vibes). Whoa. Bobby had the good oxygen running into his cannula that night. At age 73 he had the most energy I have seen in a couple of years easily, and when he did his trademark single note slam toward the end of a song he stared down at the key looking cocky and proud like Ali standing over a fallen opponent. He was amazing. Sanborn was really quite awesome and impressed me again as a great and powerful player. Billy Hart was rock solid also at age 73 and had a great style that varied from pounding to plush brushing. The most enlightening performance was Joey D. I have seen him before and liked but did not love. In this quartet he was awesome laying down bass lines and leads alike. Completely amazing on the B3 and completely in awe of his fellow musicians. The best news of all is that everything we heard will be on a Blue Note record being released in June. I can't wait.
