The 2005 documentary Metal: A Headbanger’s Journey raised the question: Is metal shocking and extreme simply to be shocking and extreme, or do some bands actually believe in the morbidity they espouse? Certainly, interviews with the steely-cold Gaahl of Gorgoroth, who responded that Satan was the band’s primary influence, and members of Mayhem, known for making necklaces out of pieces of their bandmate’s self-inflicted shotgun-blasted skull, raised some hairs. So it’s somewhat reassuring that members of fellow Norwegian black-metal band Dimmu Borgir count margaritas among their favorite beverages and U2 and Chris Isaak among their favorite bands. They’re currently on tour in support of their latest, In Sorte Diaboli, an epic composition of operatic influence, industrial grind, and melodic black metal. They play with Unearth, DevilDriver, and Kataklysm at the Warfield on Sunday, May 13. 7:30 p.m., $25. MySpace.com/dimmuborgir
