This is not really my kind of music, but since he's my nephew (ok, great-nephew), I thought I'd put out this url in case anybody else is into this stuff. His mother tells me he is very good. ;
I'm not a good judge of whether or not this is good stuff, but I'm sure she wouldn't lie to me. He has a web site, but this site has a bunch of his clips. To me, it's listenable for short periods. Don't think I'd listen to one of his albums through in one sitting though.
Anyway, for what it's worth;
