About the festival

Outdoor Selection Festival is a medium-sized open-air electronic music event featuring Psychedelic and Progressive Trance, held at the RSA Talmatte site in Effingen, Switzerland. The most recent edition took place from June 12 to 14, 2026, and has already concluded. For 2026, organizers introduced a large Tentickle Tent over the main floor to protect attendees from weather conditions that had caused problems in previous years, including the mud disaster that forced a last-minute cancellation in 2024. The next event on the calendar is the Summer Closing, scheduled for October 3 to 4, 2026, at the same location.
