Promotion for tonight’s show in the Voodoo lounge was bound to raise some eyebrows with a line-up featuring Dying Fetus, Goatwhore, Malevolence and Fallujah. The band names alone leave no doubts that the gig is not for the faint-hearted, nor for fans of One Direction. But the 200 or so fans of brutal and technical death metal that have congregated are certainly in for a treat.
