Click on "Knock on Wood" and prepare to be blown away.

He's also on the video on the Larrivee website.  I have no idea how he does some of the things he does.  I ordered his CD, which is pretty good but starts to all sound the same after a while.

I've heard a couple of his songs with vocals, and like them a lot.
