Frédéric Yonnet 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. His ability to play chromatic scales on a diatonic harmonica gives him access to twice as many notes as the instrument is designed to deliver. Wikipedia*
