WFMU 91.1 FM, licensed to East Orange, New Jersey, is America's longest-running freeform station — a listener-supported institution where DJs have complete freedom over what they play. Owned for decades by Upsala College before becoming independent, the station broadcasts from Jersey City to the New York area and is famous for its chaotic annual fundraising marathon, its comedy and its music shows that can veer from 1920s 78s to new noise in a single hour. Nothing else on the dial sounds like it.
