ahh. Mr. Bungle. (Mike Patton is a bloody legend)

Arcturus and Big Dumb Face are amazing...in their own ways, lol.

i second Gorguts, although the only album that could be really considered avant-garde is Obscura, the other three album are more brutal death but still very very kickass

Hey, cool discussion!
I just found a website dedicated to avant-garde metal:

avantgarde-metal .com

Many great weird bands featured there, also many of those mentioned here!

(Unfortunately I cannot post the link, because I have written less than 15 postings. So maye someone of you could post the right link?)

Avantgarde-Metal.com ??
