I'm absolutely addicted to Primus Right now. Probably in order of the CD's i have it would go like this

Frizzle Fry
Sailing the Seas of Cheese
Brown Album
Pork Soda
Tales from the Punchbowl

Also Claypools side projects are pretty good too. I have Les Claypools Frog Brigade 'Purple Onion' Good CD, nice use of the instrument which he calls a "Whamola" a single stringed fretless bass which he uses a drum stick to play with. Les Claypool and the Holy Mackrals is pretty decent too, but probably my least favorite.

If anyone has Antipop/Colonel Claypool And Bucket of Bernie Brains/Flying Frog Brigade Part 1 please say if there good or not.
