He was a former disc jockey of the groups Different Teep (ex-group of Manu Key & Lil Jahson), Ideal J and former member of the collective the Mafia K'1 Fry.

Amid his work Mehdi has remixed various electronic acts and composition soundtracks for many French and international films.
Being recognised for his efforts and budding into one of the French underground hip hop music scene's premier producers, since then he has pushed the boundary's by mixing hip hop and electronic music. Collaboration with such notable artists of the likes of Daft Punk, Cassius, MC Solaar, Futura 2000, and Asian Dub Foundation among others.
Mehdi released his first full-length LP in 2002 (The Story of Espion), and his second successive album, Lucky Boy, in August 2006. With the popularity of cross genre hip hop into such areas as indie and electronic music, popularization by Timbaland and other labels from the United States in more recent years had assisted to bridge the gap between dance genres.
"The internet has changed music." With the rise in popularity of online media, particularly sites such as MySpace, he knows it has given him a medium of expressing and putting out his music, but Mehdi has never been one to jump on the bandwagon.
The American audience may be familiar with Mehdi's I am Somebody used in a 2007 commercial for XM radio.
