Explore the “relationships between sound, music and nature” at this guided tour, during which participants are taken to multiple, outdoor locations to enjoy live music by Charles Rivera and Bobby Barbour. There will also be a lecture by David George Haskell, author of “The Songs of Trees” and professor of biology at the University of the South. Feel free to bring a blanket or chair, a flashlight for travel, food and nonalcoholic drinks. Check the event page at facebook.com/sonicbernheim for any last minute changes.
