We're talking this week with David Commanday, Artistsic Director of the Heartland Festival Orchestra. They're finishing their 7th season by joining forces with the Peoria Area Civic Chorale to perform Carl Orff's "Carmina Burana." The program also includes music by Dvorak and Arvo Part. Commanday talks about all three works, about the logistics of bringing the orchestra and chorus together, and about the community partner featured in this concert. The performance is tomorrow night at 7:30 at Five Points Washington.
