PHOTOS: MAYHEM, KEEP OF KALESSIN, HATE, AND ABIGAIL WILLIAMS AT THE TROCADERO IN PHILADELPHIA, PA, NOVEMBER 4, 2011

It’s almost the weekend, so it’s time to get tr00ly, tr00ly evil with this shit — like, black metal tr00ly evil. And who’s more tr00 — or evil — than Mayhem?

The band is currently in the midst of a North American headlining run with Keep of Kalessin, Hate, and Abigail Williams (tour dates here). MetalSucks’ own Alyssa Lorenzon attended the tour’s recent stop at the Trocadero, and, HAIL SATAN!, she captured some truly shadowy, scary shit. See all of her awesome photos after the jump!
