GWAR is a satirical thrash metal musical group formed in 1985. The band is best known for their elaborate sci-fi/horror film inspired costumes; raunchy, obscene lyrics; and graphic stage performances, which consist of humorous re-enactments of political and moral taboo themes. The band also performed fire dancing until the character "Slymenstra Hymen" left the band. Their costumes are generally made of foam latex, styrofoam, and hardened rubber. The costumes cover very little, with the rest of their bodies accentuated with makeup. They further their production in concert by spraying their audiences with imitation fluids. Most of the fluids are made of water and powdered food coloring which, for the most part, flakes off or washes out easily. The thicker fluids are made from a clear seaweed extract called carrageenan which is also used in ice cream and milkshakes. GWAR does not use syrups or stage blood because they dry solid, wrecking their costumes. In concert, GWAR has been known occasionally to perform their encore without costumes.
Another trademark of GWAR's live show is their lampooning of celebrities and figures in current events. Victims of GWAR's antics have included O.J. Simpson, John Kerry, Mike Tyson, George W. Bush (as well as every other President since Ronald Reagan), Jerry Garcia, Osama Bin Laden, Michael Jackson, Al Gore,John Mccain, Barack Obama,Hilary Clinton, Paris Hilton, Arnold Schwarzenegger, Adolf Hitler, and many others. The band also makes frequent references to political and historical figures, fantasy literature, and mythology. For instance, the song Whargoul makes reference to Minas Morgul as well as the eternal warrior of Michael Moorcock. GWAR also has many references to H. P. Lovecraft themes (Antarctica, Yig, Giant Penguins, Fleshy Insanities, etc.). In addition, the title of their fifth album RagNaRok comes from Norse mythology.
