I'm trying to find times in which Phish played in front of a rainbow, which may or may not have occurred on 1992-08-17. But then rainbows got me thinking of marriage equality, which makes me want to look for wedding gigs, especially since the clip sounds like it took place was in a house or studio. Alas, I can't listen to 1988-05-28.

Fishman's snare sounds odd, Page's use of the B-3 is a little unique, Mike's extra poppy, and Trey's tone strikes me as 1990-ish. I'd say it's in the key of A but it could also be related to E, but that's type II...

At this point we have to work collectively on this one.
