Mr. Oizo (pronounced Monsieur Wah-zoh) is the pseudonym of French music producer Quentin Dupieux.

Dupieux is most famous for his electro track ‘Flat Beat’, which became a hit all across Europe in 1999 as it was featured in a series of Levi's jeans TV commercials. Dupieux also directed the ad, which featured a yellow puppet named Flat Eric nodding his head to the sound of the track while riding in a pickup truck. After “Flat Beat”, Oizo released his first album in 1999, Analog Worms Attack, featuring a single of the same name. In 2005, Oizo released his second album entitled Moustache (Half a Scissor). In 2006 and 2007, Oizo produced remixes for Kavinsky, Jamelia, Cassius, Scissor Sisters and, most recently, Calvin Harris. Dupieux's first feature film, Steak[1], was released in France on June 20, 2007. [2] [3]

Mr. Oizo's latest EP is called Transexual and was released on Ed Banger Records. The EP features a re-working of the 1979 disco track “Do It At The Disco” by Gary's Gang. The track appeared on Oizo's MySpace page in 2006 under the title Patrick122.
