Cave In is an American rock band formed in 1995 in Methuen, Massachusetts. The band was originally formed by vocalist Jay Frechette and vocalist/guitarist Stephen Brodsky. They named themselves Cave In as a reference to the Codeine song Cave-In. The initial lineup also included guitarist Adam McGrath, drummer John-Robert Conners, and bassist Justin Matthes. Their first release was a self-titled 7" on Aaron Turner's Hydra Head Records. Matthes would leave the band in 1997 and his replacement, Andy Kyte, would also leave the following year.
