Epitaph Records is an American independent record label owned by Bad Religion guitarist Brett Gurewitz. Throughout the 1980s and 1990s, most acts signed to the label were punk and pop punk acts, while there are many post-hardcore and emo bands signed to the label as well. A large portion of the record label, known as Hellcat Records, is owned by Tim Armstrong, frontman of the punk rock band Rancid. Several sister labels also exist, such as ANTI-, Burning Heart Records, Hellcat Records, and Heart & Skull Records that have signed other types of bands.
