I don't know how long that set would have to be to look good on paper.

Those songs look good because they're songs that we associate with bygone improvisations. If you put all those songs in a typical-length set with a Guyute / YEM clusterbomb of composition at the end it's going to look more cluttered than good, IMO.

The most amazing thing on earth would be if they were desensitizing us to increasingly standardized versions of the "heavy hitter jam songs" because they were sick of basing improvisation in the same 20 or so songs. And then on the flip side, our 5 minute Ghosts can start segueing into 14 minute Roggaes or Stealing Times or whatever. There is so much territory to explore and no reason to keep following well worn paths.
