Fascinating read. It is interesting to see themes pop up in the flow of the middle of the album. I dont have the knowledge base and skills you do so forgive the mistakes I make as I try to explain what I am hearing. Maybe you can help me articulate this better: In Waiting all night, we have an E-flat major with the addition of the minor 3rd, Gflat, that adds the color to the outro. Next up is Wombat, hopping to that 3rd, Gflat major and ending in its 3rd, though minor, B-flat, then up, Snow, again a jump to the 3rd, and again a switch from major to minor, to D. Next up, Devotion to a dream, another jump to a 3rd, back to Gflat. Then, in a move just like we saw through Wombat, we hop 3rds and go from Gflat back to a B-flat minor for 555, and we return to B and allude to the beginning theme of the opening frame, as mentioned. I think it is also worth noting that the jam between 555 and Winterqueen, the only that could be described as Type II for the night, clearly very tweezer reprise in its structure, alludes to the chords Trey is playing in Wombat in the Bflat funk session.
