Yeah dude, do you know how many people got Metallica tattoos in the 80s, and now do you think they are showing off their tattoos with St. Anger banging in their stereos?? Personally, I would either get something universal tattooed, like a crest of some sort, or something important to me. But if you really want something Opeth tatooed, try to find a great pic of a black rose, I think that would look badass, and if you find out Opeth are gay, or if they start some kind of a cheese cult, no one would be able to accuse you of "having the black rose immortal tattooed on your ass!".
