Don't like their earlier output, for the most part. I regularly listen to Scenes from a Memory through A Dramatic Turn of Events, with Scenes from a Memory and Train of Thought being the only two I listen through the complete disc.
You can get your money's worth out of them; the discs are 70+ minutes long. The ones I don't listen to in completion, I get 40+ minutes of solid stuff.
Sample them. You'll likely find something they've done that turns your crank.
