With a debut album coming in just a few short days, Avicii has launched a promotion in New York City and Boston in which patrons can buy a limited edition Avicii tee shirt in exchange for a wristband that will allow them admission into a secret Avicii show in New York City. The show is scheduled to be held October 10th at New York’s Roseland Ballroom and is an 18+ event (you can still purchase the shirt if you’re under 18, you just won’t be awarded a wristband). The catch? The limited edition tees are only available at Denim and Supply Stores on University Place in New York City and on Newbury Street in Boston. Being his only scheduled stop after his album release, this show is sure to be something special for Avicii fans. If you’re in New York or Boston I suggest snatching your shirt and wristband soon, for the promotion is while supplies last only.
