Cave In is an American rock band that formed in 1995, in Methuen, Massachusetts. After several members changes in the late 90's, their lineup solidified with the 1998 release of Until Your Heart Stops through Hydra Head Records. Their early albums were prominent releases in the independent 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—a release that saw a return to Cave In's earlier and heavier sound.
