First off, this disc is great. You can't deny that. I would buy this very, very fast. It's mature, it's moody, it's the kind of disc you can pop in and listen to front to back and feel like it's once fluid piece.It's Tool's 'Dark Side of the Moon'.But...........Tool's progressive efforts here in Lateralus are good, but could be better. By today's "Metal" standards, Tool just blew everyone out of the water with this. But, by "progressive" standards, this leaves a bit to be desired.Does that make sense?Tool have upped the level of their play and have stepped into another arena of music. But, there are many other bands inside this arena and they are doing it better than Tool. At least right now. I predict Tool will expand on this and their next disc will be REALLY AMAZING! Let's hope so.
