A lot of the improv moments are surprisingly humorous, and some are near brilliant. Claypool scores the best lines as talentless and technically obsessive drummer Lapland “Lapdog” Miclovich. Among some of his more memorable scenes are his explanation of the bands origins and how the lightning bolt of their logo differs from the Grateful Dead, his musings on the blown glass sex toys he crafts in his spare time, and his 8-hour drum kit set up when the band makes it into the studio to cut their first album.

Jonathan Korty as keyboardist Herschel Tambor Brillstein also has some funny scenes as he practices yoga and spouts Eastern philosophy, continuously burning sage to rid the band of any bad spirits. Bryan Kehoe plays guitarist Steve “Gordo” Gordan, and most of his humor comes from his obsessions with Jerry Garcia, including a brilliant scene featuring the Garcia Tortilla (think the Virgin Mary’s face in toast). Bassist Steve “Aiwass” Trouzdale, played by Adam Gates, lives in a treehouse in his parents’ backyard, so as you can imagine, there’s some pretty humorous stuff there as well.

These guys obviously know the genre they’re mocking, so there are plenty of funny jam band cheap shots, and not surprisingly, pot plays a prominent role. There are also a few celebrity cameos, including the Grateful Dead’s Bob Weir, Phish’s Mike Gordon, and comedy writers/actors Seth Green and Matt Stone. The music numbers, unfortunately, are not very memorable, which I find surprising given Claypool's achievements with Primus (although the overplayed "Burning Man" song is pretty funny the first time around).

There isn’t a whole lot more than what I’ve outlined here, but if you’re a fan of mockumentaries or someone who’s even mildly amused by the jam band scene, this movie is worth seeing once.
