I have this acoustic passage in a song that is very inspired by how the first part in "Benighted" is played, although it sounds nothing like it.
That happens to me a lot, I will aim for a certain sound or feel that I hear in an Opeth song and it ends up coming out completely different, though in my head there is still a connection. I think Mikael touches on that aspect in the Rehearsal Tapes DVD when he speaks of Burden. He said he was going for a certain Scorpions' song vibe, though the song came out sounding nothing like the actual Scorpions track.
To Mantraschism:
I'll have to check out your tunes tonight as I'm stuck at work for the time being.
