Arcade Fire debuted new music at a secret show in New Orleans last night, The Times-Picayune reports. Before their headlining set at the Voodoo Music + Arts Experience festival tonight, they played a small show for about 175 friends and friends of friends at an empty Secondline Stages film studio, where they tested out some new material described as “dynamic, danceable rock” with “a sharp focus on heavy topics but percussive-heavy beats and a flavor of disco.” All cell phones were confiscated at the door, so there’s no actual video to post, but keep an eye out for their Voodoo set tonight.
