If you wanted to impress someone, which track?

Neil Young's Unplugged version of "Unknown Legend".

In addition to a fine live recording of a great tune in general, I can point out the exact location in the recording of the guy in the audience who, understandably, goes "Whooo" about 1/3 of the way through!

Thom Rotella Band, trk #3, Naima--play loud only if your system can handle it!

Roger Waters' "Amused to Death" gold CD. The entire CD is recorded in Q sound and has sound staging and imaging unlike anything I have heard. You will hear things sound like it is to your far right and left and on some of the tracks , behind you with only 2 stereo speakers. I have had people searching for the other "hidden speakers".. It's amazing. You must be positioned perfectly between the speakers. Let me know if you try it.
