Trey is all over the place in Piper, taking the lead with searing notes that go off wildly in all directions with lots of movement up and down his fret board. Adventurous, but not especially focused until about the 13 minute mark, when it settles down into a completely different animal that's much less frenzied.
Sand is 14 minutes of repetitive jamming in that uninteresting, unexciting style that makes many of the 99-00 jams not age especially well.
Bathub Gin has a brief peak, with Trey the band really heating up at around 11 minutes. Twist is a little ragged at first, but gets going nicely without being overwhelming. Lots of slower stuff afterwords, a reflection of the quiet and attentive Japanese crowd. Sure would be nice to hear them revive The Inlaw Josie Wales one of these days.
Check out the Disease and Piper for some interesting 2000-style jamming.
