I thought I saw Trey trying to get Fish to speed up early in Weekapaug and when he didn't, that's when Trey started shredding really fast and dirty chords to force everyone else to play to his tempo. Which they did. Then I thought My Soul was his way of setting the tempo himself and using an easy blues to get everyone locked in together. Which it did. And then the rest of the night was bliss. Looked to me like Trey just took control after that weird first bit.
