Deliverance!
I can't believe that so many people doesn't like it! It awesome! It's got everything: from heavy riffs, cool solos (often two per song - respect), well-performed lyrics & growling to those mellow parts you die when you hear. I like all the songs on Deliverance.
I'm a die-hard Opeth fan and I like Damnation as well. But it's a bit to mellow for me and for Opeth I think. But don't get me wrong it's a professional and extremely beautiful album. I sorry because the best song on Damnation - "To rid the disease" - I've recently learned, is directly taken from Dan Swanö. Ofcuze it's not the same song, but the chorus is very similar.
If you want to listen to Opeth at its best listen to Still Life, Blackwater, Deliverance and Ghost Reveries!
