The CD in my car is Oysterhead. If you've not heard them, then I'd recommend perusing their site. Its an amalgamation of Les Claypool (primus), Trey Anistasio (phish), and Stewart Copeland (police). Very unique sound, they've only put out one album back in 2001 so I'm sure somone has heard of them. In my opinion the best side projects that any of the artist has ever done. Favorite band at the moment is phish, then danzig, then bauhaus. Most listened to song this week is "Army's On Ecstasy" by Oysterhead.

The full song that they demo off the album is Mr. Oysterhead, its a dandy song to listen to really loud at work. I love rocking the cubicles.
