Keeping track of the ever-expanding number of summer music festivals just got a little more difficult, thanks to the folks at LivingSocial. The location-based deals website is organizing its own event, dubbed the Backyard Festival, and they're busily lining up an impressive list of performers.

ABC News reports that Aerosmith and Joan Jett will be among the headliners for the festival, which is scheduled for July 13 at Randall's Island in New York City. While the complete lineup is still being finalized, LivingSocial is also promising "bocce ball, slides, see-saws, photo booths, art and crafts, swing sets, Giant Twister and much more."

"This is the summer backyard party to end all backyard parties," boasted CEO Tim O'Shaughnessy, vowing that "When the weather gets hot, Americans have always gathered with friends in their yards to listen to great music, eat great food, share cold beers, and create lifelong memories. LivingSocial's Backyard Festival will propel that beloved summer ritual to the next level with legendary bands, world-class cuisine, top-shelf wine and beer, and games for all ages."

The Backyard Festival will be one of only three North American tour dates scheduled for Aerosmith this summer; the band is currently set to play a Connecticut date on July 10 before heading to Randall's Island, to Japan for a brief string of dates, and back to the U.S. for a Milwaukee show on August 30. Jett, meanwhile, will be leading the Blackhearts through a full complement of dates throughout the summer and fall -- check out the complete list at her official site.
