Self-taught composer, turntable prodigy, and visionary producer, DJ Mehdi was the only French artist to bridge the gap between two seemingly opposing worlds: rap and electro. Thirteen years after his sudden passing, this documentary series, directed by his childhood friend Thibaut de Longeville, sheds light on the role of this free spirit in the rise of these two musical scenes in France during the 1990s and 2000s.
