Check out his acoustic concert that he filmed in Vienna.
I enjoy his work with Beth Hart. As a player in a band JB is great because he knows how to check his ego and let the singer stand out. I feel the same way about Satriani—his solo work bores me, but I enjoy his playing in Chickenfoot.
I agree about him (and Satriani) being really good in the band context. I may be in the minority, but I like Joe. I think he got stuck with the stigma of being another SRV wannabe when he was starting out. He was just a kid back then, and has done a lot of different projects since; Black Country Communion and Beth Hart to name a few. For yet another side of Joe, check this out.
I actually think that was worse than his regular music. I'd rather listen to Galactic.
