He's a cool guy but a little too flipped out for my taste, at least rather often.

I saw his band Freak Kitchen live a few years back with a guitarist friend of mine who actually know that guy personally, and it was a quite cool gig. The band (trio) was really good and they grooved.
There's a great deal of humour in his music. Both in the lyrics (FK is not instrumental) and in the music itself. My favourite Freak Kitchen songs are "Appetizer", "Taste My Fist", "My New Haircut", "Vaseline Bizniz", "Propaganda Pie". I love the solo in Appetizer, it's one of the funniest solos I know yet not too flipped out

. Taste My Fist is very dynamical with strange rhythm changes and has a cool bluesy/jazzy part too. My New Haircut and Vaseline Bizniz are more "plain" songs but with funny lyrics. Propaganda Pie has a cool bassline in the verse.
Worth checking out.
