Joshua Ralph, better known as J. Ralph, is a musician whose songs are regularly featured in modern commercials. His music can be found in advertisements for Volkswagen and Volvo. Surprisingly enough, J. Ralph is unable to read or write music. His lack of training in music theory may explain the diversity of his songs, which make his work as a whole difficult to classify. He has recorded two CDs: The Illusionary Movements of Geraldine and Nazu and Music to Mauzner By.
