Mr. Bungle, an American experimental rock band, was formed in Eureka, California. The band's eclectic style incorporates heavy metal, avant-garde jazz, ska, disco, and funk, enhanced by Mike Patton's versatile singing.

Mr. Bungle recorded their first demo, The Raging Wrath of the Easter Bunny, which featured a fast, lo-fi death/thrash metal sound with touches of ska. Instruments utilized on the album included a train whistle, saxophone, bongos and a kazoo.

Mr. Bungle released their second demo, Bowel of Chiley, which featured a greater ska presence, as well as the sounds of jazz, swing and funk.

Mike Patton became the lead vocalist for Faith No More after the band heard him on the first Mr. Bungle demo. Patton continued to be a member of both bands simultaneously.

Mr. Bungle released its third demo, Goddammit I Love America!, which was musically similar to Bowel of Chiley and described by Mike Patton as "funkadelic, thrashing, circus, ska."

Mr. Bungle recorded OU818, their final demo tape, which was the first release to feature both tenor sax player Clinton "Bär" McKinnon and drummer Danny Heifetz. At the time of this release, Mike Patton described Mr. Bungle as a "weirdo funk band".

Mr. Bungle was signed to Warner Bros. Records, with the label releasing all three of their studio albums during the 1990s. It has been speculated that Patton's success as frontman of Faith No More was the primary reason Warner Bros. signed the band.

Mr. Bungle created a music video for the song "Quote Unquote", directed by Kevin Kerslake. However, MTV refused to air the video because of images of bodies dangling on meat hooks.

Mr. Bungle's debut album, Mr. Bungle, produced by jazz experimentalist John Zorn, was released. The record mixed metal, funk, ska, carnival music and free jazz, but was normally described as funk metal by music critics.

Mr. Bungle supported Disco Volante with their first world tour, performing across North America, Europe and Australia.

Disco Volante was released after artwork delays and the band members' many side-projects. The new album displayed musical development and a shift in tone from their earlier recordings.

Theo Lengyel left Mr. Bungle due to creative differences.

Mr. Bungle reconvened to record new material after a two-year break, which saw Faith No More split.

Mr. Bungle's third album, California, was released. Ground and Sky reviews have described California as Mr. Bungle's most accessible and, while the band's signature genre shifts are still present, they are less frequent, with succinct song formats resulting in an album that the Associated Press called "surprisingly linear".

Mr. Bungle appeared on the 2000 edition of the SnoCore Tour, performing alongside alternative metal acts it had influenced, such as Incubus and System of a Down.

Mr. Bungle played its last concert in nearly 20 years in Nottingham, England.

Patton announced that Mr. Bungle had disbanded.

It was announced that Mr. Bungle would reunite in February 2020 for three shows in Los Angeles, San Francisco and Brooklyn, performing The Raging Wrath of the Easter Bunny in its entirety.

Mr. Bungle collaborated with comedian Eric Andre, who introduced the band at the beginning of their show, and Jed Watts, the original drummer of Mr. Bungle.

Mr. Bungle formally announced that the band, joined by Scott Ian and Dave Lombardo, were currently re-recording The Raging Wrath of the Easter Bunny in addition to the previously unreleased songs and covers performed during the reunion shows, with an expected release on Patton's label Ipecac Recordings in the fall of 2020.

Mr. Bungle released a cover of "U.S.A." by The Exploited, featuring a hardcore punk sound.

Mr. Bungle officially announced that the album, now titled The Raging Wrath of the Easter Bunny Demo, would be released on October 30. Alongside the announcement, they released an animated music video for the single "Raping Your Mind" directed by Eric Livingston.
