For shorter jam, it’s between the 2/16 Round Room and 2/26 Moma.
For longer jam, I’ve really been digging the 46 Days from IT for a long time. It’s like my go to “jam that Vern would hate because it’s so spacey and dissonant” jam. The part on the DVD they show of this jam is fucking money, but the other 30 or so minutes of it are great, too. I especially like how they slowly worm their way back to the main theme again.
I still think that the 2/28/03 Tweezer is the most fluid, consistently brilliant post-hiatus jam. Other jams from post-hiatus have better sections, but that Tweezer doesn’t have a wasted second.
