Meet the members of IAM, a very popular French rap group originating from Marseille. They discuss their successful career and their latest album, Arts Martiens (Martian Arts).

Discover a unique instrument called the ondes Martenot, a precursor to the synthesizer named after its inventor, Maurice Martenot. This electronic piano-like instrument, once a musical sensation in the 1930's, quickly fell into disuse, but is experiencing a revival thanks to Christine Ott, a talented pianist who adopted this unusual instrument and has worked alongside such musical greats as Radiohead and Yann Tiersen.
