What are your favorite progressive rock albums?

How is Dream Theater progressive? I'm a sucker for their stuff, but they rip off Yes/Genesis/Rush/other 70s prog rock bands rather than creating anything truely new. When I think of modern progressive bands I think of truly original stuff like Tool, Incubus, or Modest Mouse.

I would disagree and call Deam Theater quite original. They, like other prog bands consistently explore their sound and never release the same thing twice. Whatever they do which can be called ripping off someone else is no more than anyone else. If you love a band and they influence you, in some way you will rip them off. No biggie, because they are my favorite prog band, and they surprise me with every cd.
 
Rush- A Farewell to Kings
Transatlantic- Bridge Across Forever(some would call it metal, but I think it is very prog rock)
Tool- Anima
John Petrucci and Jordan Rudess- An Evening with John Petrucci and Jordan Rudess.
Dream Theater- Awake(Metal I know, but there are a lot of rock songs on it, and it's my favorite cd in the world.)
