It was actually on the back of your Camilla George post, Trimmy. He's been advertised as playing at Turner Sims for a couple of Months but I've only heard a little bit of him. I followed through on a bit of information on Camilla George and see She's playing with him at The Jazz Cafe. Thought I'd do a bit more digging and came up with this!
If the line up at Band on the Wall is the same as Turner Sims, have a look at Nir Felder, the guitarist (he plays on the previous Keyon Harrold video). Very interesting, slightly odd technique and sound on his solo stuff. Rhythmically and melodically he reminds me a bit of Jeff Buckley, but then he rips out some killer solos.
