Set 1 is a mix of covers and originals, including "Thela Hun Ginjeet" (King Crimson) and "Shine On You Crazy Diamond" (Pink Floyd).

Its initial lineup featured MIRV's Marc Haggard on guitar, Skerik on saxophone, and both Jack Irons (ex-Pearl Jam and Red Hot Chili Peppers) and Primus' Tim Alexander on drums.

The band consisted of Jay Lane on drums and Todd Huth on guitar, who had worked with Claypool in Sausage (which in itself was a re-formation of the first line up of Primus), guitarist Eenor, who got a place in the band by winning a mail-order competition, Jeff Chimenti, the keyboardist from Ratdog (Jay Lane also has worked with Ratdog), and Skerik continuing on saxophone.

Reviews noted that although Claypool was turning towards jam band, the cover selections were adventurous and the cross over brought together a unique combination of fans.

This band had much the same genesis as the Frog Brigade; Formed to play at the Bonnaroo Festival of that year, it has since gone on the road, and recordings have become subsequent live albums.

As of August 2011, the Frog Brigade has not recorded any new material since Purple Onion, and the band has not gone on a major tour since Summer 2003, but has occasionally re-formed to play other one-off shows and music festivals.

In 2023, Claypool reformed the band for a tour entitled "Summer of Green," featuring an almost entirely new line up of Sean Lennon on guitar, Harry Waters on keyboards, Paulo Baldi on drums, and Mike Dillon on percussion.
