Gravity Records is an underground independent record label from San Diego. It was formed in 1991 by Matt Anderson, a member of the influential underground band Heroin. It has been central in developing and promoting the "San Diego sound" - an idiosyncratic form of post-hardcore with loose, chaotic musicianship and vocals, initiated by Heroin, Antioch Arrow, and Clikatat Ikatowi, as well as Mohinder from the Bay Area and Angel Hair from Colorado. The sound is associated with the first wave of screamo. Gravity has also branched out into other forms of experimental or independent music, releasing seminal early works by Unwound, Black Dice, The Rapture, and a full-length from Man Is The Bastard.
