A little more than a month after front-alien and frequent Fox News commentator (no, really) Oderus Urungus and his merry band of self-proclaimed “Scumdogs of the Universe” in Gwar held yet another Crack-a-Thon to fund the comedy-metal beasts’ ongoing freebase fixation, the group returns to Irving Plaza, angering its cleanup crews yet again with more rampant spillage of fake (we assume) bodily fluids. By popular demand, Gwar never change, and their stage show remains the ultimate in gross-out rock. Wear a raincoat and maybe bring a cup. With Every Time I Die, Ghoul and Gunfire-N-Sodomy.
