Joshua Rifkin is an American conductor, pianist, and musicologist, primarily known for his work in the realms of classical music and early music performance. Born on September 24, 1935, he gained significant recognition for his interpretations of the music of J.S. Bach, particularly through his recordings of the "Goldberg Variations" and the "Brandenburg Concertos." His performances often emphasize historically informed interpretations, utilizing period instruments and practices. Rifkin is also credited with reviving interest in ragtime music, notably through his arrangements and performances of Scott Joplin's compositions. His 1970s recordings of Joplin’s work helped to popularize the genre and contributed to the ragtime revival movement, influencing both musicians and composers. In addition to his performance work, Rifkin has written extensively on music theory and history, contributing to a deeper understanding of various musical styles. His impact on the music world can be seen in his advocacy for historically informed performance practices and his role in the popularization of early American music genres.
