I think EVIL portrayed his emotional connection to Still Life quite nicely. And before I comment, this is totally subjective reasoning, and my taste in no way reflects that of any other human on this earth (I've seen so many disclaimers, I felt it was my time to come up with one).
This to me proves that Opeth from a musical standpoint incites more deep emotion than most other bands. Try having this conversation with a Limp Bizkit album.
BWP was my 1st entrance into this Opeth world, and to date, it is still my favorite Opeth album. This statement is not based on the "entire" album concept - only that there are 3 songs on BWP that totally envelope me, and keep me in the 4th dimension while listening to them - The Funeral Portrait, Bleak, and Blackwater Park. On my favorite song list, these 3 are in my top 10 of ALL songs I like (30% - best average).
There are only a handful of albums that I can admit I love from cover to cover. BWP is one of them, along with Grip Inc-Power of Inner Strength and The Tea Party-Edges of Twilight. Opeth is my favorite band, if not for the 3 songs I mentioned, it's for the musical talent on most of their works. These albums contain at least one amazing song on them, and even though I don't necessarily like every song, these albums work from beginning to end.
As far as Still Life, I haven't listened to it enough to form a concrete opinion, other than if I only heard that Opeth album, I would still consider them one of the most talented metal bands on the planet.
