One of the 7 circulating shows from the MOI 10 Years Anniversary tour, never seen as lossless according to The Catalogue.
When I located the tape flip in Inca Roads, I recalled a little 10 min snippet of this show that was in circulation before this tape surfaced in 1999. Didn't that snippet include Inca Roads? I knew I had it as filler on a tape somewhere in my messy collection, but I couldn't find it. Luckily enough, Drew had it, and yes indeed: the missing piece of Inca Roads was there!
Still this is not the complete show: Son Of Orange County cuts near the end, and the recording doesn't resume until late in the More Trouble Every Day solo.
