The OK Mozart International Festival takes place in Bartlesville each June, bringing world-class classical musicians and ensembles for a week of concerts, chamber music, and educational events. Founded in 1985, the festival has grown into one of the most respected classical music festivals in the region, drawing performers and audiences from across the country.
The festival uses multiple venues around Bartlesville, including outdoor concerts in Johnstone Park. The combination with the National Biplane Expo (usually the same week) makes early June a particularly lively time to visit the city.
