Harmonicist Frédéric Yonnet has played with Stevie Wonder, Erykah Badu, John Mayer, Ed Sheeran ... even Prince. But his biggest fan and supporter is Dave Chappelle, who worked with the Normandy native on Dave Chappelle's Juke Joint, a series of intimate parties featuring Yonnet, his Band With No Name, and an all-star cast of unannounced special guests.
