settledowncity-deactivated20120 asked: For screamo you should check out Archives. For math rock, Faraquet and Sweep The Leg Johnny are two bands I've been listening to a lot lately. For post rock check out If These Trees Could talk, and Natural Snow Building's album "The Dance of the Moon and the Sun". They are a mix of a lot of stuff like ambient, drone, folk, etc but you should like them if you like post rock.
I’ll check all those out ASAP. Thanks!
