Cave In is an American rock band that formed in 1995 in Methuen, Massachusetts. The band's lineup solidified with the 1998 release of Until Your Heart Stops through Hydra Head Records, and their early albums were prominent in the metalcore scene. The band later experimented with other genres, receiving 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, later reforming in 2009 with the release of the Planets of Old EP, followed by the White Silence LP in 2011, both of which saw a return to Cave In's earlier and heavier sound.

Until Your Heart Stops is the debut album by metalcore band Cave In. It was released in 1998 on Hydra Head Records. Until Your Heart Stops has been regarded as a landmark release in the metallic hardcore genre.
