The crusty sci-fi monsters of the thrash-metal band GWAR have a problem. Apparently, the 43-billion-year-old lead screamer Oderus Urungus is up to his devil horns in debt thanks to his insatiable taste for crack, and now needs your help. Come out and make a donation to this worthy cause at the Crack-A-Thon, a two-night twisted variety show, co-hosted by Mr. Urungus and Balsac the Jaws of Death, featuring gory Grand Guignol–style skits, footage of Oderus terrorizing the streets of NYC, and live celebrity interviews with the likes of Andrew W.K., Lloyd Kaufman of Troma, Mecronos of Dethrace, and Jimmy Gestapo of Murphy’s Law.
