Black Album by Metallica. It's my DSOTM. I have literally heard it on every stereo I've owned. That an I use various acoustic recordings of low brass instruments. Brass is what I am most familiar with since it is the instrument that I primarily play. So I like to see how trombone, baritone, euphonium, and tuba are rendered. Acoustic guitar does not interest me as much. But overloaded marshall stack is another matter. :-) For that I use Pantera's Live 101 Proof, Gorefest's Eindhoven Insanity, and NIN's And All That Could Have Been.
