Rooted in the improvisational millennial groove of '99, although perhaps more repetitive and even plodding at times, Fishman largely leads the jam until about 8 mins in, when Trey adds some space vamp.

At 10 mins in, Mike changes course, and the jam takes on a menacing, heavy tone, continuing to build in intensity until a looped-out groove arises, and slow rolls its way to a thunderous conclusion. Not as wonderfully weird as 12/4/99, or as funky and fun as the 12/31 performance, but still an incredible three versions to end the century.
