I don't consider myself an audiophile, but I have thrown buckets of money at my audio system and I do try to get the best out of it by optimizing the setup.  Years ago, friends and I began using the LP of this album when evaluating audio components.  To understand why, just play "Toccata" at a relatively high volume.  This disc has lively, dynamic music that has been blessed with outstanding recording quality.  To appreciate it at it's best, I recommend that you turn out all of the lights and crank up Toccata - that's what I dubbed the standard darkness test.  Towards the end of the tune, there are some incredible drum sounds.  Classic Fresh Aire !
