A performance by St. Louis’ own Gateway Men’s Chorus opens this special program featuring the documentary “Gay Chorus Deep South,” which was the Tribeca 2019 Audience Award winner. The film follows the San Francisco Gay Men’s Chorus as it embarks on a tour of the American Deep South. In response to the divisive 2016 election and a wave of discriminatory anti-LGBTQ laws in Southern states, the chorus — joined by the Oakland Interfaith Gospel Choir — brings a message of music, love, and acceptance to communities and individuals confronting intolerance. Frequently moving — and often funny — “Gay Chorus Deep South” features the expected array of extraordinary performances, but it places equal emphasis on the conversations and connections that occur between concerts. The evening also includes the short “Ladylike,” in which a young queer woman in the American South comes to terms with her sexuality.
