“Classical musicians of African descent have existed on the margins of obscurity for centuries — in the classroom, the concert hall, the record industry, and on the radio,” says Terrance McKnight, evening host at New York classical radio station WQXR. In this radio special for Juneteenth, he talks to Wynton Marsalis, Martina Arroyo (one of the great operatic sopranos of the 1960s and ’70s), composers Alvin Singleton and Leslie Dunner, Nashville Symphony principal oboist Titus Underwood, and other guests as well as listeners about working as an African-American in the classical music industry.
