Day & Night ringleaders Derek and Daniel Koch are again adding sky diving to their hard-partying brunch. On Saturday, DJ LA Riots will leap from a plane with six Red Bull synchronized divers and land on a beach at Gurney’s Inn in Montauk. The DJ will then start spinning at the bottle-popping July Fourth weekend bash. For Memorial Day, the Koch brothers offered Dom Pérignon bottle service via a sky diver at Gurney’s, but the stunt sommelier couldn’t make the drop due to the awful weather.
