I always noticed the acoustic bit in The Baying of the Hounds right before the ending heaviness sounded A LOT like the music for Tristram in the original Diablo. Seriously give that a listen and you'll hear it. Tristram had great music, such a sad atmosphere, maybe because no one ever moved...

Anyways I definitely agree with all this, Diablo has excellent music and I have had many moments playing that game where I just kinda went, "Holy shit! Sounds like Opeth!"
