This kind of stuff is a big reason I got into the Disco Biscuits.

Obviously they don't have the kind of depth as Phish in their improvisation, but what they DO have is a consistent dedication to segueing - at high speed and high volume- into songs in different keys. And their approach to it is so methodical and mathematical that you can anticipate it. A lot of "And now this note changes, and then that note changes, and then that note changes, and now we're all hitting this same chord at the same time"

It's simplistic, but devestatingly effective to have that "Shift into the Bowie ending" in every song.
