The Muny, a nearly 11,000-seat amphitheater nestled in Forest Park on the outskirts of St. Louis, bills itself as the nation’s oldest and largest outdoor musical theater. This summer’s slate presents the usual slew of crowd-pleasing musicals peppered with Broadway talent, kicking off with a staging of “Les Misérables” featuring 2023 Tony nominee Jordan Donica (“Camelot”) as Javert. From there, the season progresses to productions of “Dreamgirls,” “The Little Mermaid,” “Fiddler on the Roof,” “Waitress,” “In the Heights” and “Anything Goes.” June 17-Aug. 25 at the St. Louis Municipal Opera Theatre, 1 Theatre Dr., St. Louis. muny.org.
