Dont diss the old stuff. "Close to the Edge" was made over 32 years ago and not even the masters themselves have topped that masterpiece.
Take "Moving Pictures" as another example of youthful experimentation never topped, not even by the originators.
Point me to music made by todays young people that even remotely breaks the same ground and pushes those 20+ year old boundries and I will be forever greatful. I dont think music exists in todays narrow electronic imprisoned vein that tops either of those two examples (and those are just a few examples of great *timeless* music) by even a wide margin.
