I have recently become a big fan of these duders. Their sound has been all over the damn place over the years, so I'll try to gauge some examples to help you find the ones you would most enjoy.

Cave In is an American rock band that formed in 1988, in Methuen, Massachusetts. After several members changes in the late 1990s, their lineup solidified with the 1998 release of Until Your Heart Stops through Hydra Head Records. Their early albums were prominent in the metalcore scene. After this release, the band started experimenting with other genres. Cave In later received mainstream recognition for their 2003 RCA Records album Antenna and its lead single "Anchor," which had an overall alternative rock style. The group went on hiatus in 2006 and later reformed in 2009 with the release of a new EP, Planets of Old, as well as a new LP in 2011, entitled White Silence. Both of these post-hiatus releases saw a return to Cave In's earlier and heavier sound.
