Hey Jourles,
Those tracks you recommended are very good tracks. I tend to agree Deliverance and Damnation are better albums when comapared to their earlier material. Im quite an Opeth fan, and have doubles of all the albums because my JW sold them to me (demon influences). Hailing from Australia, I seen Opeth in April earlier this year, and unfortunately, they have postponed their Damnation tour to Late March as it is not economically viable.
At the moment, my favourite track is Face of Melinda (usually the Damnation setlist closer). I got into Opeth through the release of Blackwater Park, as did the majority of most Opeth Fans. Get this! My friend got Rid of Deliverance because of the front cover (in the mirror a disturbing face). Master's Apprentice is the best track of the album, however, the track Deliverance (near the end) includes the most oustanding part on any of their albums. Martin Lopez great drumming on Deliverance, wouldnt you agree?
Ive been meaning to get my hands on "In absentia" for a while now but record stores dont have it. Thats good you listen to Opeth, and dont think of Satan, you're the first. My friend who threw out Deliverance still has Damnation, Blackwater Park and Morningrise.
