BTPISIO is the best.. it's the most innovative song on the album, after quite a few listens i'm sure this is my favorite. I especially like the waltz section. oddly, I like the final tracks best on all their albums.
I honestly don't know why so many people voted for Deliverance.. that song seems to stretch on indefinitely with all kinds of repitition, and as far as Master's Apprentices, I like that one, but the middle section of it gets a little tedious.
I think the second best is "A Fair Judgement"
