It's almost hard to consider Gwar "shock rock", since gasping instead of laughing would mean you've somehow managed to discount the campiness.
I've never paid much attention to GWAR aside from the occasional Beavis and Butthead placement in the '90s, but the band playing when we walked in late sounded exactly like what I always imagined they might have when bringing them up as a hyperbolic extreme (a sort of Godwin's Law for metal, perhaps) with way too many loud guitars,indecipherable vocals, etc. Unfortunately, they were sensibly attired. "What, no costumes tonight?" I immediately remarked. "Screw that." Upon turning to leave, though, we spied the merch booth and realized that it was the opening band (unfortunately I can't tell you who it was because there was too much blood dripping from their logo to actually read it).
GWAR, on the other hand, turned out to have a surprisingly listenable dose of perfectly competent high-powered id-metal. Listening was not the point, however. Outlandish costumes aside, you also have the accompanying rock-opera storylines and the Gallagher-esque constant spray of hopefully-washable liquids into the crowd from a variety of severed limbs and other distressing sources (penises, giant cannons -- the latter had some serious range, as did the former, I guess, all things considered). It's almost hard to consider it "shock rock", since gasping instead of laughing would mean you've somehow managed to discount the campiness.
