The best “Superjam” you can think of . . .

My last post brought me back to a conversation that kept coming up between me and my friend at this year’s bonnaroo.  We were discussing the “superjam” they have every year, and were coming up with ideas for the best musicians (living or dead) to play together.  Our favorite involved Battles’ John Stanier, Radiohead’s Jonny Greenwood, and The Band’s Garth Hudson.  I want to start a discussion on the topic so leave comments about who you think would compose the best superjam.  Keep the discussion going . . .
