Great read so far, definately respect how well versed you are in your musical tastes. I agree w/ what you said about the Slayer show, in that AOS -> JS was incredible. And yes, Gary has helped Slayer's sound a bit. When did you see them that they were so sloppy? I saw them in 2010 in Glens Falls, and thought they sounded great.
