|Hmmm...out of all of these, I'd say focus on #12, that's a good one. When you're done with it, grab "Colony" and/or "The Jester Race" and/or "Come Clarity."|
If you're willing to invest a bit more time, focus on #3 (along with it's brother EP's). It takes a while to catch the subtle nuances of the discs that make them so good, but they're there.
