This month, the New York Public Library (NYPL) is celebrating the centennial of Cage’s birthday with a live event on September 27 and the publication of John Cage’s Prepared Piano, a new edition of their Point iBook periodical series. The evening event also offered NYPL an opportunity to highlight the ongoing development of John Cage Unbound: A Living Archive, a new website that showcases the John Cage manuscript collection housed at NYPL’s Library for the Performing Arts, as well as videos in which professional musicians, students, and others explain how they prepare and perform works by Cage.
