Re: i$e's Magical Music Megapost
For someone not accustomed to heavier stuff, I'd almost always say something like Ghost Reveries or even their acoustic album, Damnation.
However, I'm gonna go ahead and tell you to listen to Blackwater Park and Still Life. Then once you've confirmed greatness, roll onto My Arms, Your Hearse (my personal favourite) and then whatever else you feel (although I'm really not a fan of their new LP at all).
On that note, 100 replies! Successful thread and I'm off to bed. Let me know your Opeth thoughts for sure.
