The ImprovBoston Mainstage is the cornerstone of professional comedic talent at ImprovBoston. Showcasing our signature style of improvisation, Mainstage blends fast-paced games, hilarious scenes, skillful storytelling, memorable music and 100% voluntary audience participation into a never-before-seen show. No rules. No boundaries. Just spectacular comedy delivered by an elite cast of the best improvisers in New England. Given the ridiculously fun and unpredictable nature of improv, we can't guarantee age appropriateness (every audience gives different suggestions); we recommend Mainstage for those who enjoy PG-13 comedy.
