I've had the fortunate opportunity of listening to this ABSOLUTE GEM! "Gem", unless I'm unearthing fossils and happen to strike a fortune, is not usually a term within the lot of my commonly used vocabulary ... But this show is unreal. The audio of the recording I heard wasn't too great, but tolerable nonetheless. It's like 1.1 hours on iTunes and features past members Marc Daubert and Jeff Holdsworth. The set list really is as good as it looks, including the 'first known performances'. The vocals are especially muffled in the beginning of the recording but start to sound clearer about 3/4 of the way through the Jam -> "Bertha". Then at the end of "Bertha" some guy (no idea who) start yelling like an absolute mad man. Really the only thing I can relate the voice to is the alien that asks for salt water in the original MIB. Ha. Download this one if you haven't. The guy's yelling nothing in particular, and stops about a minute into "Can't You Hear Me Knocking".
