Awww man I had a great answer prepared about Before The Dawn being the biggest disappointment in a while...oh well. At least I can still ask the question. And hey, Scenes From A Memory is great...I just re-discovered it a while ago. Sure, some sappy/crappy songs, but stuff like Home and Finally Free really makes up for it. Anyway, opinions.
Crimson I definitely. I've not managed to listen to Crimson II in its entirety yet, but I can't see it surpassing the first one anyway.
Who's the best: Kevin Moore, Derek Sherinian or Jordan Rudess?
For an obvious answer, check the NP.
