The previous reviews are right about a few things; the lot scene, the band's inconsistency really beginning to emerge, etc. But...
I saw plenty of bad shows in '99 and '00 but this one actually ranks among my favorites. It's so swampy and thick. Perfect summer night show. Only other outdoor show from these years i enjoyed as much was the Polaris thunderstorm experience. About 10 minutes of ambient noise before the drop to 2010. My Left Toe ties almost the entire set together. Deep YEM. Make no mistake, the second set was WAY out there, and pretty much an uninterrupted run of intensely psychedelic stuff.
Bad shows aside, this show is exactly why '99 has grown on me over the years. It's great atmosphere music. Their sound was so mindbending back then, and spread across a much larger canvass than they're using now.
