Totally agreed with EyeAm. Deliverance is far from a bad album, but it's lacking a certain emotional quality that previous Opeth albums had. When you think about songs like Advent, Demon of the Fall, Drapery Falls, etc., there's a beautiful atmosphere that goes far beyond the musicianship. Those songs get through to me much more than most other music, which is why Opeth is one of my favorite bands. No longer true for Deliverance and Damnation - both incredible albums on a technical musical basis - but kinda soulless.
It would also be interesting to see where Deliverance and Damnation would stand if Agalloch hadn't released The Mantle back in August. That masterpiece of an album seriously affected my musical tastes, and might account for why I didn't like the new Opeth as much.
