Mathematical rock has something to do with post-rock, and it is also called indie rock style, which has a similar musical orientation to indie rock. Where post-rock has obvious jazz influence, mathematical rock is like the reverse of a coin-its music is heavy and complicated, full of incomprehensible time signs and intricate phrases. And this kind of music is more rock than post-rock, because it is usually played by a small band with guitar as the main instrument.

Mathematical rock reached its peak in the mid-1990s, when bands like Polva and Chá vez had independent rock musicians on university campuses who specialized in this kind of music.

Personally, I prefer 90 Day men. You can try it.
