I tend to stay with death, black, industrial types. Dragged into Sunlight, Carcass, Bongripper, Watain, Mercyful Fate, Sun O))), Birthday Massacre, Electric Wizard, Monolord, Eyehategod to name a few.
Took a friend to see Dragged into sunlight, he wasn't ready for that. Tripped him out. Then a year or so later took him to see Sun O))) and I don't think he trusts me with shows where he doesn't know the band now haha.
