The HORST Festival is a nexus of innovation in the arts, architecture, and electronic music. Expect fantastical stage settings—last year a ship-like structure emerged from the lake to become a dance floor—and tastefully curated set lists. While nighttime dancing gives festival-goers a workout, daytime offerings exercise the mind and include lectures from installation artists, interviews with writers-in-residence, and collective community art projects. —C.J.F.
