Basically, they need to put Madahoochi on the Field or Barn stage and let them finally be seen / heard :D
I'd also love to see The Flaming Lips there, just to see what they do with that large of a stage.
DSO was there the first year I went, and yeah would love to see them there again. Can't wait for Trey to make a comeback there either, though I'm not a huge Trey fan. MMW with Scofield would just be ridiculous.
Wouldn't mind seeing David Byrne or Ween make a 10klf appearance someday, either.
