Koo Koo Kanga Roo is an American comedic dance-pop duo from Minneapolis, Minnesota, consisting of vocalists Bryan (Bryan Atchison) and Neil (Neil Olstad). Billed as an "interactive dance party duo" and described as "the Beastie Boys meet Sesame Street", Koo Koo Kanga Roo showcase a colorful live show that relies heavily on audience participation, featuring overtly silly sing-along songs that are typically accompanied by their own individual dance move. The duo has toured nationwide, performing for both children's events and at mainstream music clubs with rock and punk bands (including Lee Hartney & The Smith Street Band), and is notable for releasing all of their recorded music under a "pay what you want" price. Koo Koo Kanga Roo have defined themselves foremost as a live band, with their performances and audience interaction being the pure core of the group, even more so than their recorded music. Bryan and Neil are the only members of Koo Koo Kanga Roo, and thus perform all of their songs against pre-recorded backing tracks played from their iPods over the venue's PA system.
