In 1968, a bankrupt classical music station in Boston went back on the air with a new format and essentially one rule: play whatever you want, say whatever you think. What followed was a radio station that, along with dissent and rock and roll, helped end a war, drive an unpopular president from office, and give a voice to people who had never had one.

WBCN gave Bruce Springsteen his first radio interview and his first live in-studio radio performance, and Patti Smith her first live radio broadcast with her band. The film also has the night Springsteen played the Harvard Square Theater in Cambridge in 1974, opening for Bonnie Raitt — the show that made critic Jon Landau write "I saw the rock and roll future, and its name is Bruce Springsteen," and that led Landau to become his manager and producer. David Bowie, Lou Reed, Jerry Garcia, Jane Fonda and Abbie Hoffman all came through the station's studios.

But the music was only part of it. WBCN ran the phone lines for Boston's antiwar movement, broadcast from the middle of demonstrations, and gave a platform to the civil rights, women's and gay rights movements when almost no commercial outlet would.

The film is built from more than 100,000 pieces of archival audio, photographs, film and ephemera from the era, much of it donated by the people who were there, including never-before-exhibited footage shot by Andy Warhol.
