Carl Demler & Beethoven Pianos Featured in Sundance Documentary: Mott Music

This documentary is about the marvelous discovery of a Piano Factory in the South Bronx and the characters that dwell within. Once a part of Mott's Iron Works in the 1880's, the largest producer of cast iron tubs of its time, now Beethoven Pianos is a place of piano restoration. Once inside, explore the synchronous lives of a piano voicer, a piano dealer, and a piano technician.
