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.
