How President Obama Won a Second Term

Two official inaugural balls will be held throughout the Washington Convention Center, along with children's concert on January 19th, though inauguration organizers have yet to announce which artists will play what events. Tickets for one of the galas, the Inaugural Ball, were priced at $60 and have already sold out; that event is expected to draw more than 35,000 attendees. For those who couldn't score a ticket, various unofficial inaugural balls will be happening throughout Washington D.C.

Many of the artists performing were vocal supporters who joined the president on the campaign trail as he sought re-election: Perry played a handful of rallys, as did Wonder (who also wrote a song for the President), Legend and Anthony.
