The Sound of America

There are many Americas. Nowadays they barely speak to each other. But during the most perilous years of the last century, one young composer went in search of a sound that melded many of the nation's strains into something singular and new. He was a man of the left, though of no political party: gay, but neither closeted nor out; Jewish, but agnostic, unless you count music as a religion. His name was Aaron Copland. On this July 4th weekend, WNYC’s Sara Fishko tells his story.
