Welcome to MOSY’s 2025
Summer Music Festival
The Missouri Symphony welcomes you to Firefly Music Festival 2025! Join us on a musical journey across four centuries, featuring both classical favorites including Haydn’s Drumroll Symphony & Dvořak’s New World Symphony, and new and exciting works from pops to film to contemporary!
Why Firefly?
“You know you’re in Missouri when fireflies light up the evening sky!”
Since the founding of our Hot Summer Nights Music Festival in 2004, MOSY has welcomed musicians and guest artists from all around the world to perform with the MSO each summer. Following our Summer of Conductors in 2022, we entered a new phase and asked our musicians what helps them feel at home when visiting Missouri. The answer was unanimous: fireflies! After that, MOSY had no doubt what the next iteration of our summer festival would be called.
We are excited to be sharing the third year of this new look with you and can’t wait to have you join us for the Missouri Symphony Orchestra's summer festival experience!
