Frédéric Yonnet (born 30 April 1973) is a French musician, producer and recording artist who is best known for his use of the harmonica as a lead in jazz, R&B, funk, gospel and hip-hop influenced music.

Yonnet has performed and recorded with a wide range of artists, including David Foster, Robbie Robertson, Erykah Badu,[4] John Legend,[5] India Arie,[6] Angie Stone, Kindred The Family Soul, Justin Bieber, Randy Jackson, The Jonas Brothers and Grand Corps Malade.

In 2001, Yonnet moved to Washington, DC, where he performed in area festivals and clubs, quickly developing a reputation as a "genre-bending" harmonica player.

Later that year, Yonnet, along with Erykah Badu and Goapele, were invited to perform at the AACW Blues Festival (Yellow Springs, Ohio) hosted by Chappelle.

In 2010, in a pioneering effort that combined technology, art and reality, Yonnet halted all aspects of production on his most recent project – recording, packaging and video – to give fans access to the raw and rough cuts of his work at various stages of the creative process.

Yonnet coined the term "Reality CD" to describe the bold concept of allowing fans to observe key phases of the production.

Yonnet's work in progress, subtitled The Rough Cut, is available exclusively to fans purchasing digital download cards at live concerts and online.
