I know about 2 ppl i can talk about metal to. There used to be this metal fan who liked metal while i was still a rap guy, but he changed a little while ago. Now he listens to Staind, Sum41, etc.
Incorrect, Pie, I went straight from Korn to Opeth......or from korn to dimmu borgir to finding out dimmu borgir sucks to opeth.
Anyway, i find a successful way is to let them hear cleaner songs first, like The Drapery Falls. Because usually an early turn off for those pussies are the vocals. If you give them something that is remotely heavy with some metal vocals but a lot of clean voice, they tend to be interested. I haven't been a metal fan very long, and I've converted 2 or 3 people already.
