This year's Northside Festival has already made a number of announcements about the acts playing the Brooklyn fest this summer. And they're still not done with the surprises: War on Drugs and Beirut have been added as headliners to the growing lineup.

With the recent release of their latest album 'Lost in the Dream,' War on Drugs will kick off the music portion of the festival on June 13 at 50 Kent, an outdoor venue in North Williamsburg. Beirut will play the following day at the same venue, making it one of their very few live performances in 2014.

Titus Andronicus, Eagulls, Chvrches, Sharon Van Etten and F— Buttons have also been confirmed for this year’s Northside fest.

Advance tickets go on sale on April 11 at the Northside Festival website.
