Oner started in 2000, trading his graffiti bombs to pens to make his first rhymes with his brother and friends in NCA Crew. After spending hours in the studio sharpening their rhymes on analogs, the crew released 3 mixtapes between 2001 and 2006, no matter the growing place of digital into hip-hop music. The crew split and Oner decided to found his own studio « Rue du Bon Son », started to get specialized into sound engineering, production and beatmaking. The notoriety of the studio became viral with the recording of the first tracks of 1995, who were big fans of NCA Crew at the time, and the first project of Areno Jazz : « Alias Darryl Zeuja ». This collaboration with Areno Jazz led to a project named XLR for which Oner did most of the productions. In 2014, XLR opened for Georgio, Flynt, Rocé, Set & Match or even the American rapper Reks. 2014 was also the consecration year for Oner and his beatmaker skills : « Paris Sud Minute » from 1995 won the « Victoire de la Musique » for « urban music album of the year » category. Since then, he keeps on producing and recording a lot of artists such as Swift Guad, Lord Esperanza, ODP, AmerGAng or H5C.
