Math Rock is a relation to post-rock, a better known indie-rock style that shares similar aesthetics. Where post-rock has distinct jazz influences, math rock is the opposite side of the same coin -- it's dense and complex, filled with difficult time signatures and intertwining phrases. Also, the style is a little more rockist than post-rock, since it's usually played by small, guitar-led bands. Math rock peaked in the mid-'90s, when groups like Polvo and Chavez had small, dedicated followings among indie rockers on collegiate campuses.
