Pardon the non-commercial interruption...
Just wanted to reply to Orpheus' previous posts and pay a compliment to Leon Thomas. At the risk of trivializing his talent, I want to say, "what a nice voice". When he's singing a lyric...no posturing just a certain naturalness and purity about it - at least in the limited listening I've done so far as a result of Jafant's Pharaoh Sanders recommendations.
If you will further indulge me in an unsolicited 2 cents on the more recent jazz bassist topic...check out Tony Levin (yes I know, not a jazz-only bassist) playing with Andy Summers. They do a great version of Afro Blue. It's on "The Last Dance of Mr. X. There was a YouTube video of them playing it live...can't find it now, however.
For Rok on in-performance interactions between musicians. On the off-chance he's not already seen it...
