For more than 80 years, the Grant Park Music Festival has been Chicago's summer musical sensation, demonstrating that classical music, performed by a world-class orchestra and chorus, can have a transformative impact on the city. Led by Artistic Director and Principal Conductor Carlos Kalmar and Chorus Director Christopher Bell, each summer the Festival offers a 10-week season of concerts, artistic development initiatives, radio broadcasts and community engagement and outreach programs. Today, it operates as a unique collaboration among the Grant Park Orchestral Association, the Chicago Park District and the Department of Cultural Affairs and Special Events.
