I do believe this was The Jammie's 2002
This was a wild show. Two stages jamming with each other. I remember TomTomClub locked into some amazing grooves. I remember Skerik blowing wild sax with Particle. I remember the love shack (see review) and John Popper playing with everyone. I remember a young girl singing and playing organ who was amazing named Grace Potter. So much more. My buddy Bob and I did not make it to the Bob Weir Jam, I think we left at 1 am it was still going strong.
