So I figured I'd mention this guy since nobody else did. Soooo... he does industrial metal. Whoo. I've noticed that with the (admittedly few) metal bands I listen to, my favorite tracks of theirs tend to be in the "industrial" genre. Probably explains why I like bands such as Rammstein. But anyways... back to the PAIN.
So he's pretty much a one-man band. Does all the vocals and instrumentals on his own (save for a few guest artists that tonic in to do solos for him occasionally), which I think is pretty epic, because he demonstrates quite a bit of fluency in a number of radically different instruments.
... I just like his music. A lot. >_> I can honestly say that so far, the only tracks I haven't liked are the ones he did that are covers of other people.
