Roudoudou first started to play with tapes and sounds in 1981 when free radios were coming through. Until 1985 he will have his own daily radio show Tout l'Univers aired on Radio Nova: an eclectic program as indicated in the program title, done with lots of cut-ups on Revox tapes. This very same year he joins the French band Oui Oui as a singer, meeting old friends Etienne Charry & Michel Gondry for several concerts. He still performs as dee-jay no longer on radios, but for Parisian parties.
