Query: A masterpiece

I hadn't heard of them before...and when I did, it was because I heard "Take the Time"...my brother had bought the CD. It's a brilliant band, still showing that there are people capable of treating music with the respect it deserves. John Petrucci, Kevin Moore, John Myung, and Mike Portnoy- this is a band with top-class names that brings on constantly top-class music. Amidst the lightning-quick finger movements racing along fretboards or synthesizer keys, the musical sensitivity is evident here, the soul, the harmony...everything for a masterpiece, a sheer lesson of musicianship brilliance, is here. Enjoy.
