Pittsburgh Steelers fan (boo!) and rising rap star Wiz Khalifa will join 2011 Sound Off! winners Tomten as part of the lineup for this year’s Bumbershoot festival.
The festival began announcing its lineup Sunday on its Facebook page and will use Facebook during the month of May to reveal one act a day that will be performing during Labor Day weekend at Seattle Center. These daily announcements all lead up to the big reval of the completle lineup for Bumbershoot 2011 which will happen on June 1. Tickets for the festival are currently on presale and cost $29 per day or $75 for a three-day pass.
