Disco Lost and Found

You know Saturday Night Fever, the Bee Gees, and ABBA but do you know the disco stylings of Christian Marclay or Jamel Shabazz? Today, a look at a new art exhibition that chronicles some of the lesser-known artists and songs of the disco era. Joining us is the curator Edwin Ramoram and Mel Cheren, the "Godfather of Disco," who founded the dance label West End Records. Also: A visit with Niyaz, a band that merges modern electronic beats with the traditional sounds of the Middle East. They’ll be part of GlobalFest, a major showcase for world music artists which is taking place this weekend at the Public Theater. Finally, we look at the phenomenon of multicasting on the radio.
