I know it's not really Dead-related, but a theory question in general. This has had me stumped for a few weeks now. During a lot of Phish jams they'll be doing something usually Dorian sounding, but then they sort of get into a different sounding, tension building, period until it culminates back into the root. It's easiest for me to hear during the jams in Chalkdust Torture, Run Like an Antelope (that's all i can think of without their stuff in front of me). The dude in the attached video tries to explain it but I am still pretty confused. As far as I have gotten in trying to figure it out is that I think it's a minor scale of some sort over the V chord. There are some serious theory people on here so I was just wondering if you could shed some light on this
