Man, what it would feel like to be in your shoes right now, and hearing this stuff for the first time all over again. I envy what you're about to hear. Welcome to the board.
In this order:
(1) Volume 8: The best album that nobody has heard
(2) Sound of White Noise: The second best heavy metal album ever, after Volume 8
(3) Stomp 442: Whenever you need your ass kicked from beginning to end
(4) The Greater of Two Evils: A collection of great tunes, recorded "live in the studio" and ending up better than any of the originals
