While I admittedly only know the 1st one, I'm still going to share my $0.02:

- 1st clip is 7/22/13 DWD, clip taken from last few minutes of jam that > 2001 (got this one in less than 5 minutes)
- 2nd clip sounds like 3.0, but I can't say for sure. Could be pretty much any ambient Phish song from any song, until you start plucking at the keyboard and realize it's in E-flat major, of all keys. That narrows down most songs except HOSE jams that modulate, esp. tweezer, and Gumbo.
-3rd clip is flat-out smacking me in the face.
