I suggest listening to the album "Sing the Sorrow" by AFI. And if you don't like the whole thing, just listen to the final track "...but home is nowhere", which is about 15 minutes long. pretty neo-progessive IMHO.

Songs in the track (but i still suggest listening to the whole thing on iTunes or Rhapsody because I can't find a full track on youtube)

The Spoken Word (poem, my personal fave)
This Time Imperfect (probably their best song. Pretty damn depressing)

By the way, I know that the Forums had some beef with some AFI fans after there was a stupid band competition some time two years ago. I've gotten over that and my opinion is that AFI is never gonna be as good as Pink Floyd, but AFI is surely better than Jonas Brothers, Fall Out Boy, and that stupid band called My Chemical Romance.
