Les Claypool, bassist of many bands, including Primus, collaborated with virtuoso guitarist Buckethead, funk keyboardist Bernie Worrell, and former Primus drummer Brain (Bryan Mantia) under the name Colonel Claypool's Bucket of Bernie Brains (a combination of all the band members' names), after they met at the 2002 Bonnaroo Music and Arts festival. Worrell, Brain and Buckethead were there to perform with Bill Laswell as Praxis. Laswell was not able to play at the concert, so Claypool invited them to jam with him. From this point, they developed the concept of this supergroup. Their concerts pushed the improvisational envelope by preparing no material and not rehearsing beforehand. At one of their shows they prepared sandwiches onstage for the audience members to eat.
Colonel Claypool's Bucket of Bernie Brains reunited in 2004 to record The Big Eyeball in the Sky, an album with equal parts instrumental and vocal songs. The band began an 18-state tour of the US on September 24, 2004. Claypool said the tour was "a traveling, oversized sock-puppet show spawned by the characters of a Tobe Hooper film and scored by Danny Elfman on bad acid." The album features only one guest, the multi-talented Gabby La La (noted as Gabby Lang on Les Claypool's Frog Brigade's Purple Onion) on vocals and sitar. She also opened on every show during the 2004 tour to mixed reviews as a solo act, sometimes with members of C2B3.
