I'm sorry to say this but you listened to their worst record!!! It's a good release, but by far their worst (in my opinion). That is the only Opeth album I wish I could have produced! I'd have done a lot of different things with that record. First, take Dirge for November off the album and replace it with Still Day and Patterns II for the standard release. Second, I'd shorten the first interlude on BWP. That goes on way too long. Third, shorten The Drapery Falls, great song, (you won't hear me say this often) but way too long. Fourth, add some content into Harvest; good song, but somewhat boring. I would leave Lepper Affinity, Bleak and Funeral Portrait alone, those are all amazing songs as is!
Don't get me wrong, I do like BWP, but I feel it could've been so much better. That and Deliverance, to me, were done the wrong way. I love Steven Wilson and Porcupine Tree, but Wilson was way too involved on those records. I wish Wilson only produced Damnation and either Swanö, Nordström or Bogren produced BWP and/or Deliverance.
