Blaring the Cream anthem "I Feel Free," WBCN went on the air in March 1968 as an experimen on the fledgling FM radio band. It broadcast its final song, Pink Floyd's "Shine On You Crazy Diamond," in August 2009. In between, WBCN both pioneered and defined progressive rock radio, sustaining a vibrant local music scene that launched such artists as the J. Geils Band, Aerosmith, James Taylor, Boston, the Cars and the Dropkick Murphys. Carter Alan was a DJ at WBCN from 1979 until 1998, and he visits our Conversations series to discuss his new book Radio Free Boston: The Rise and Fall of WBCN, the story of a city in tumult, of artistic Freedom, of music and politics and identity, and of the cultural, technological, and financial forces that killed rock radio. Carter Alan is a DJ and music director at WZLX in Boston, where he hosts the mid-day show and "Sunday Morning Blues". He is the author of two books about the band U2 - Outside Is America and The Road to Pop.
