I wonder why nobody mentioned Who's Your Favorite Son, God?, which is an awesome band. They sound like US Maple on acid with young Robert Plant on vocals.

Cool thread by the way.

huh
they don't sound mathy to me!

Well, I've read somwhere that they play math rock and their approach to making music is similar to the one of US Maple, at least in my opinion.
How about these records, are they mathy enough?

mmm the him discog is pretty spotty, to me they qualify as post-rock (stupid conversation....)
and storm and stress have more to do with improv rock in spite of the Don Cab etiquette...
i dunno... it doesn't matter, good bands..
