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. He was also a long time the quasi-appointed producer of the group 113 and carried out the nearly all the production of the albums for Different Teep and Karlito. Amid his work Mehdi has remixed various electronic acts and composition soundtracks for many French and international films.
Being recognized for his efforts and budding into one of the French underground hip hop music scene’s premier producers, since then he has pushed the boundaries by mixing hip hop and electronic music. Collaboration with such notable artists of the likes of Daft Punk, Cassius, MC Solaar, Futura 2000, Asian Dub Foundation and Chromeo among others. “Coming from a rap music background, it’s always nice to collaborate within other music genres…Paris is very inspiring because a lot of people are making great stuff, music and in other arts related fields also. My music and philosophies revolve around beats and blues, that’s how I would try to describe it.”
Signing to cross-genre label Ed Banger Records, Mehdi and Pedro Winter (aka Busy P) were working on various disco-hop sounds the two as far back as 1997. Together they hosted a very successful monthly night at former Paris nightspot Pulp. “I like to be the DJ, I love it so much. I love to try new things. You would never get into this business to be bored, or you would hope not.”
Mehdi released his first full-length LP in 2002 (The Story of Espion), and his sophomore 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.
