LAUDED AS THE first gourmet music festival, Outside Lands has become a Bay Area tradition for music lovers, foodies and stand-up comedy fans alike. The fete has drawn and continues to feature high-profile artists; this year’s headliners include Metallica, The Who, Lorde and A Tribe Called Quest. Beyond music, attendees will have access to refreshments from more than 80 Bay Area restaurants, over 40 Northern California wineries, close to 30 West Coast breweries and a collection of the region’s best cocktail bars. All that dining and imbibing means lots of trash, but worry not: the festival is one of the world’s most sustainable large-scale events and the proof is in the numbers — last year 91 percent of the waste was reused, recycled or composted. Outside Lands takes place August 11–13.
