Frédéric Mainçon is a French guitarist, vocalist, and filmmaker engaged in interdisciplinary creative work.

Active in France's experimental music scene, Mainçon explores the intersections of sound and image through collaborative, multimedia projects.

"Music composer, film director, multimedia author, sound designer, writer, Jean-Jacques Birgé considers music essentially in the audio-visual relationship, or at least in its confrontation with other forms of artistic expression.

Founder of Disques GRRR, he was one of the first synthesists in France in 1973, and with Un Drame Musical Instantané the precursor of the return to the cine-concert in 1976. If his first electronic work dates from 1965, he composes as well for symphonic orchestras that he improvises freely with musicians from the most diverse backgrounds. For his "radiophonic" creations and his multimedia shows (live zapping on the big screen, fireworks, choreographies...), improvisation and preliminary writing merge, the original electroacoustic treatments are integrated with traditional instruments to create evocative musical fictions that he calls musique à propos.

From 1995, he became one of the most popular sound designers in multimedia and a specialist in interactive musical composition, seeking to deepen the effects of meaning and develop an ever-wider range of emotions. As part of his work on major exhibitions, he recently worked at the Louvre Museum, the Cité des Sciences et de l'Industrie, the Grand Palais, the Panthéon, the Palais de Tokyo, the ZKM...

Alongside around fifty vinyls and CDs, his website drame.org offers 105 unreleased albums (191 hours!) for free listening and downloading.

He has been running a daily, activist and supportive blog for 20 years and gives conferences on the relationship between sound and image."
