Founded in 1949, the Aspen Music Festival and School is regarded as one of the top classical music festivals in the United States, noted both for its concert programming and its musical training of mostly young-adult music students. The typical eight-week summer season includes more than 300 classical music events—including concerts by five orchestras, solo and chamber music performances, fully staged opera productions, master classes, lectures, and children’s programming—and brings in 70,000 audience members.
