CRSSD Festival is an electronic dance music event held biannually in March and September at Waterfront Park in downtown San Diego, California. Launched in 2015 by the event production company FNGRS CRSSD, founded in 2013, it features performances across three stages with a mix of electronic and independent music. The festival has grown to attract around 15,000 attendees per day, as seen in the Spring 2024 edition, and showcases a range of artists from established acts like ODESZA, Kaytranada, and Paul Kalkbrenner to rising talents and live electronic performers. It emphasizes diverse dance music styles, including house, techno, and indie electronica, without notable album releases as it is a live event series. CRSSD is known for its daytime outdoor setting in an urban park with lawns and fountains, providing a contrast to typical nighttime rave culture, and for high-quality production including advanced audio systems on stages like The Palms.
