By the time spastic indie pop/alt/rap duo twenty | one | pilots make their upcoming return to Nashville, Sept. 21 at Marathon Music Works, nearly a year will have passed since their last proper Music City headliner, a sold out outing at Cannery Ballroom. More recently, the group played Vanderbilt’s Rites of Spring, and, in addition their Cannery performance, found their way last year to Bonnaroo and a prior smaller show at 12th & Porter. Clearly Nashville loves twenty | one | pilots, and we’re not alone: their 2013 smash breakthrough, Vessel, has earned numerous accolades, spawned five music videos, three radio singles (and counting), and has enabled the band to tour the globe to their biggest audiences ever. Sharing the stage with acts like Paramore and Fall Out Boy, and garnering a reputation for their explosive live sets and unparalleled energy, twenty | one | pilots have become a certifiable indie sensation, and are smashing their way into the mainstream, poised to have their best year yet. Pick up a ticket beginning Friday, May 16, at 10 a.m. to see what all of the fuss is about.
