I've heard him a few times: once at Sweet Basil in 1998, once a little before that at the Detroit Jazz Festival, and I think I caught him one other time in NYC - maybe at Sweet Basil again, a couple of years later. I honestly think this guy has the #1 live show I'd like to hear today. He's so powerful: manages to play the alto with the weight of a tenor.
DB - was Pharaoh Saunders playing with him? His last album, "Beyond the Wall", was recorded with Pharaoh on tenor, Brian Blade on drums (he's been playing with Kenny Garrett for a while now, so I wonder whether he's the drummer mentioned by mjosef?), Robert Hurst III on bass and Mulgrew Miller on piano. Also has some efforts from Bobby Hutcherson on vibes. I wonder if it's the same touring band?
If you want to hear him, he'll be touring various parts of Europe for most of the next few months. But he'll be in Newark, NJ on April 28, and at Iridium in NYC from May 2-6. And excitingly for me, he's due to play the Detroit Jazz festival again on September 1!
