John Ayer plays the famous Flentrop with which E. Power Biggs is forever associated for both his radio program and his advocacy of its tonal qualities. If these CDs are played in a computer, many pictures of the organ and Biggs are displayed as the music plays. Also accessible from the CD is an Adobe Acrobat file containing Barbara Owen’s account of the organ’s creation for Busch Hall at Harvard.
