In 1958, with Emile de Antonio and Robert Rauschenberg, Jasper Johns formed Impresarios, Inc., which sponsored two performances of new music and dance in New York. Performed by pianist Adam Tendler with vocalist Joan La Barbara, all the works in this program reflect the close collaboration and inter-relationships of Jasper Johns with John Cage and Merce Cunningham, or were performed at the Impresarios, Inc. events. Most notable is the now-legendary 25-Year Retrospective of the Music of John Cage at Town Hall in New York City that took place on May 15, 1958.
