I LIKE this a lot. Luke introduced me to math rock. Here is Battles doing "Atlas." (The guy with the semi-fro is a famous jazz musician's son, and the drummer is from Helmet.)

Anyone with more info about math rock, chime in. I'm up for learning all I can here!

My friends Derek or Craig could probably expound upon it at length.
Tool's stuff is a lot heavier/darker than that video you were linking to. Which is not to say that you won't like it, but I've never really gotten the impression that you were much into that genre.
I think Lateralus is probably their most art/math/progressive album to date, though their latest one 10,000 Days is probably just as proggy.
How's stuffs with you?
