Ras I Ray is his name, he sings, too. I like his playing a lot, and the concept of the band is superb. Pretty trippy arrangements.
I'd love to see their newest show, doing Sgt Pepper, (Lonely Heart's Dub Band, of course) but I haven't been able to yet.

There are a few posters here who know more about him than I do, he's been on the NY reggae scene for a while. There's some info here from the Easy Star site:

Doesn't he use Ampeg gear live?
