GWAR is thrash metal's answer to the more mainstream satire of Spinal Tap. Gory, sexually perverse, and scatological in the extreme, GWAR claims to consist of all-powerful interplanetary warriors descended from aliens stranded in Antarctica and initially created from the lowest filth in the universe, who have come to Earth to sexually enslave and/or slaughter the human race. The group performs in bizarre costumes and their stage show has been known to feature fake pagan rituals, corpses spewing washable bodily fluids on the audience, and occasionally a giant mechanical maggot.
