It sounded like so much of a true KVMR 89.5 FM broadcast event: the 40th anniversary of the Bethel AME Church of Marysville Choir performing in Nevada City on Martin Luther King Jr. Day. Still, it’s going to happen, according to the long-serving Bethel Choir director Zenobia Brown, who was 35 years old when the first KVMR MLK Day concert took place. “Forty years, four decades of meaningful concerts, we’re so grateful to Nevada City and KVMR. In recent years, the Nevada City Trinity Community Choir has joined the Bethel Choir in the festivities. The more, the merrier, and the Trinity Choir will be onstage at the church as well.
