+1 Not to mention that audiophiles all over the world use this as a standard test tool - The entire album is a masterpiece and well renowned to be one of the best mastered albums of all time. As such it;s often used by professional music installations and reviewers to test new kit. Tom Morello once mentioned that the band have used exactly the same kit since they first got together and he personally has used the same $500 amp and guitar his entire life! A perfect Circle - Thirteenth Step : Was also a fanatically mastered album and a personal favourite. Spineshank - Height of Callousness : Probably has the most listening hours of my life, I can still remember the first time I heard Sythehetic, and of course New Disease is a sensational cult classic covered by a crazy number of bands. Bob Marley - Legend : Okay so I cheated slightly there, but dear god it's a fantastic compilation of the man's work.
