from people arguing over what is and what is not Math Rock...

The obvious answer would be -
If you like Battles, check out Don Caballero.

is kinda future style madness.... Pivot could be good for ya. No idea what Math rock is really there was a good artical on it on here a while back.

...I'd suggest Standards by Tortoise. I was listening to this again recently and was struck how similar in tone and feel it is in places.

end of.

All very different but all worth a listen, in my opinion:

not that anybody ever really described those bands as math rock.

into the last.fm tag search and you get a rid good mix.

NO TIME SIGNATURES = NOT MATH ROCK.

Doesn't matter what they sound like or whether they use polyrythyms...

hella are excellent.

70's Genesis has some math rock elements.

(Not saying I like Genesis)

Well this is for me a great sub genre, but its becoming cringe worthy now days, considering this made and played best about 10-15 years ago!!!

There are also many post-rock bands like Mono and Godspeed You! Black Emperor that use "mathy" time signatures, there's lots of different stuff out there.

¡Forward, Russia! are a good shout for math-rock, especially their latest offering, 'Life Processes'.

I wouldn't say much post-rock was math-y, apart from A Silver Mt. Zion maybe
