I agree with whoever said The Sky Moves Sideways is amazing. That album is pure spaced out rich textured music and just puts (me at least) in a special place when I listen to it. Not a lot of albums can do that.
Anyhow, I hardly ever have favourites for things, espescially music. So i'm not gonna vote. One minute I like The Sky Moves Sideways, next I like In Absentia, Lightbulb Sun, Up the Downstair etc etc. I have to say tho, that Deadwing will probably never be my favourite. not to say thats a bad record or anything, cuz when it came out I loved it and still do, but I just don't dig it as much as I do other PT albums in the long run.
