Album production is one of my bigger interests. So here's the rankings in my book, soundwise:
1. BWP - Not my fave album, but the sound is amazing. Very much alive, powerfull, tight and smooth at the same time, nails it all.
2. Damnation - Amazing sound. Just perfect. Tho an all-mellow album is not as challenging to mix has a diverse one.
3. Still Life - Not what you would usually call "a good mix" or a fat production, but it has a certain atmosphere to it, the still life feeling. Also the sound was new in metal at the time, low amount of distortion on the guitars and lots of layering. Cool stuff.
4. Watershed - The new album simply has a great sound, and isnt that haunted by the usual plastic-perfection style of Jens Bogren. Love listening to it. The low-mixed growls are irritating tho.
5. Deliverance - This production is not a big fave among the fans, or the band for the matter. Me, however, I really like it for some strange reason, I think it's once again the "feel" of the album that does it. It shouldnt be as low as #5, but I guess competition is fierce.
6. Orchid - Kind of demo-like production, but also the whole old unisound style, which is very "winterish" in style and gives Orchid a very cool sound in parts. Lack of clicktrack is not that suiting for Opeth tho.
7. MAYH - A very metal production. Not bad at all, but not that good.
8. Ghost Reveries - Plastic fantastic. I prefer hearing these songs live.
9. Morningrise - Sorry guys, this sound sucks. Both Swanö and Opeth would agree. Good songs, but terrible production.
