Swedish black metal band Watain ignited a succession of vomiting from audience members this weekend during their concert in New York. The Satanic rock band used pig's blood in their performance, which made its way onto concertgoers and in turn caused some of them to vomit and cry.

TMZ broke the story of the concert held in Brooklyn, New York, and according to their statement following an interview with the band, real pig's blood was used.

In a YouTube video of the concert, the lead singer Erik Danielsson, is seen presenting the audience with a goat skull full of blood. Danielsson takes a drink of the blood, sprays it out of his mouth and onto a skeleton that is on the stage, he then proceeds to throw the blood on the crowd.

Aside from screaming and projectile nausea, the distemperment of the audience members had no follow through, TMX police stated that no one has complained and there has not been any word from the health department.

Watain identifies themselves as Satanists. Vocalist Danielsson has said openly that unless contributed by members of other bands, he writes all lyrics, and their song topics are "based upon, Satanism, and Devilworship." Danielsson believes that a belief system shared by all members "is a must in order to do something as intimate and personal as music," according to metalhammer.teamrock.com. As a group, Watain support the Misanthropic Luciferian Order, which is a cult order, founded in 1995. It now goes by the name of Temple of the Black Light.

News of outrageous satanic practices have been making headlines recently. Earlier this month a man was taken into custody for sacrificing and eating a woman in Tennessee.
