Toward the end of the inaugural Boston Calling Music Festival last May, the organizers had a surprise in store for the crowd that had packed City Hall Plaza. Right before the indie-rock band the National closed out the two-day event, the first of its scale and scope in the heart of the city, a video announcement was made: A second edition would happen in September, bringing to town Vampire Weekend and Passion Pit as the headliners. Audible gasps rippled through the audience, which was estimated at 19,500.
Now comes word that a third installment of Boston Calling is set for May 23-25 (Memorial Day weekend) again on City Hall Plaza. The lineup, curated by Aaron Dessner of the National, is especially heavy on artists from indie-rock and Americana circles. Jack Johnson, Death Cab for Cutie, Modest Mouse, Tegan and Sara, Phosphorescent, the Head and the Heart, Jenny Lewis, and Kurt Vile and the Violators are on the roster, and organizers say one more big act will be announced later.
