For people who never stopped being fans of mathcore, I recommend listening to the e-card on The Minor Times' website. The full CD is streaming and these guys will be on tour with Anodyne.
i guess it depends on your definition of mathcore or whatever. alot of people threw DEP into that, but i really only think bands like botch, cave in, etc really fit that description. and I think the minor times sound a ton like botch.
