Part 1: Live at the Woodstock, Orange County 28 March 1983 (about 7 months before recording Show No Mercy). The live show is great, but it has been around and is actually one of the earliest SLAYER gigs filmed on video.
Part 2: The highlight of this CD is the 31 December 1983 rehearsal recorded in Tom's basement. Very rare and another chance to hear their best material in a non-live setting, a few weeks after the debut LP was released. Killer!
