===2004–2005: Band in a Bubble and ''Mish Mash!'' and ''#?*!''===
{{main|Mish Mash!|Pillowhead}}
In 2004, Regurgitator created and participated in the ''[[Band in a Bubble]]'' project; a new reality TV-inspired media stunt sponsored and broadcast by Australian music channel, [[Channel V]]. The band entered a small glass recording studio, built in [[Federation Square]] in the centre of [[Melbourne]], to record their new album; their first on new label [[Valve Records]]. Pedestrians could look into most rooms of the "bubble" and could watch the band work, or tune into a 24-hour digital cable television channel and watch their work on that. Nobody could enter or leave the bubble, a la ''[[Big Brother (TV series)|Big Brother]]''. In addition to the three band members, their longtime Australian producer [[Lachlan Goold|Magoo]], engineer Hugh Webb and Channel V host [[Jabba (presenter)|Jabba]] were all also locked into the bubble with the band.

The first single from the session was released in October 2004 as "[[The Drop (Regurgitator song)|The Drop]]" and the album, ''[[Mish Mash!]]'' was released in November 2004 and it peaked at number 52 on the ARIA Charts.

In August 2005, the band released the ''[[Pillowhead|#?*!]]'' (or ''Pillowhead'') EP which contained B-sides from ''Mish Mash!''.
