Day Trip is Insomniac's connoisseur festival, the mega-fest machinery pointed at the underground. Held in Long Beach each summer, it trades the mainstage-EDM spectacle of its siblings for a daytime, house-and-techno program built for heads: the deeper, groovier end of dance music, curated with a tastemaker's ear and a lineup that reads like a well-kept secret rather than a stadium bill. It's the Insomniac event for people who love the scene's roots, proof that the same company behind the biggest festivals in the country can also throw the coolest smaller one. For SoCal's house and techno faithful, Day Trip is the summer date that matters most.
