Gwar, often styled as GWAR, is an American thrash metal band formed in Richmond, Virginia in 1984, comprised of and operated by a frequently rotating line-up of musicians, artists and filmmakers collectively known as Slave Pit Inc.
 
Easily identified by their distinctively grotesque costumes, the core thematic and visual concept of Gwar revolves around an elaborate science fiction-themed mythology which portrays the band members as barbaric interplanetary warriors, a narrative which serves as the basis for all of the band's albums, videos, live shows and other media. Rife with over-the-top violent, sexual and scatological humor typically incorporating social and political satire, Gwar have attracted both acclaim and controversy for their music and stage shows, the latter of which notoriously showcase enactments of graphic violence which result in the audience being sprayed with copious amounts of fake blood, thus regularly leading Gwar to be labeled as a &shock rock& band by the media.
 
Fueled largely by the controversies surrounding their concerts, Gwar experienced brief mainstream notoriety during the first half of the 1990s, receiving regular airplay on MTV as well as frequent in-character guest appearances on daytime talk shows, satirizing the topics of censorship and media violence. Though the band's mainstream popularity declined by the end of the 1990s, Gwar has retained a dedicated cult following. Since their formation, Gwar have released thirteen studio albums, two live albums and numerous singles among other recordings, and have sold over 820,000 records in the United States. The band's extensive videography consists of both live recordings and long-form feature films, most notably 1992's Phallus in Wonderland, which earned a Grammy Award nomination for Best Long Form Music Video. Outside of music and video, Gwar have expanded their franchise into a now-discontinued line of comic books, trading cards, a board game and even signature beers, barbecue sauces and e-liquids.
