Do you know Gwar? Somebody does - the band has existed for more than 25 years after starting up in Richmond, Va. GWAR.NET

Gwar is set to destroy the Rialto Theatre once again on Saturday along with some of its like-minded friends, and as fans have come to expect, it should be sickening and fun.

The band has now been around for more than 25 years after starting up in Richmond, Va., and it is surviving with an ever-rotating cast that pulverizes, grosses out and amuses audiences everywhere. Its fans rank among some of the most loyal around.

Gwar is a bit of a cartoon act known for raunchy lyrics, absurd horror-inspired costumes and performances filled with a strange liquid spewing into the audience, all in the service of its strange crossover thrash-metal sound.

The band members are more or less characters, all sporting names like Beefcake the Mighty and Balsac the Jaws of Death. Its notoriety has led to worldwide album sales that top 30 million.

The Gwar folks are known for elaborate stage shows, and they are bringing an impressive roster of opening acts this time.

Self-proclaimed black-swamp-speed-metal band Mobile Deathcamp of Toledo, Ohio; death-metal newcomer Infernaeon of Tampa, Fla.; and New York punk legends the Casualties share the bill.
