ANTI- is an American record label founded in 1999 as a sister label to Epitaph. While Epitaph's focus has mostly been on punk rock, ANTI-'s roster includes country ( Merle Haggard), hip hop ( Sage Francis, The Coup), reggae ( Michael Franti), soul ( Bettye LaVette), indie folk ( The Swell Season, Saintseneca), rap rock ( One Day as a Lion), indie rock ( Islands) and Tom Waits.
Headed by Andy Kaulkin, ANTI- first gained attention by releasing Tom Waits's Grammy Award-winning Mule Variations in 1999. Other veteran recording artists such as rhythm and blues singers Solomon Burke, Bettye LaVette and Marianne Faithfull have signed onto ANTI- after leaving other labels.
