Co-sponsored by CityCenter Danbury, the music will be performed on the roof of the Patriot Garage, directly behind Danbury's CityCenter Green on Ives Street.
Organizers say if you park in the city garage, you'll have easy access to the location by elevator. If it rains, the concert will take place at Broadview Middle School on Hospital Avenue.
The program's special treats include sixth-grade cellist Julian Shively performing a movement from Cello Concerto No. 1 by Kabalevsky.
Aspiring conductor John Berger, winner of the 2012 Golden Baton, will conduct a Sousa march.
