In the middle of Breckenridge’s Blue River, Russick Smith plays his cello on a small, grassy island. With the audience assembled on stones along the river banks, he gently adjusted the microphone away from the instrument. “I’m playing a duet with the river,” he explained so that people could hear both his music and the water as it lapped against the island. While Smith does play music indoors in traditional settings, he is increasingly finding new ways to play concerts outdoors, too.
