The Sweetlife Festival will expand to two days for the first time in its six-year history on May 30-31, announced organizers Sweetgreen Tuesday.

Sweetgreen, a DC-based chain of salad restaurants, will host the Sweetlife Festival again at Merriweather Post Pavilion in Columbia, Md., with an expanded lineup across two stages.

Performers this year include Kendrick Lamar, Calvin Harris, The Weeknd, Pixies, Charli XCX, Billy Idol, Phantogram, Marina & The Diamonds, San Fermin and others. The festival also promised a “handful of local DC-area artists.”

Tickets go on sale to the public at 10am on Friday, March 6, through Ticketfly. But presales are available for those who use the Sweetgreen rewards app on Wednesday, March 4, and those who follow the salad company on Instagram on Thursday, March 5.

The festival also offers “the best in food and experiences,” according to the organizers with art installations, play areas, and partner chefs like Erik Bruner-Yang, José Andrés and Nick Wiseman. Sweetgreen will publish full details on the food and experience offerings later this spring.

The Sweetlife Festival is produced in partnership with I.M.P., which books concerts at Merriweather Post Pavilion and the 9:30 Club, of course. For more information on the festival, visit, http://www.sweetlifefestival.com.

Tickets will be available online or at the box office of the 9:30 Club.
