Among those chosen to perform are Katy Perry, Smokey Robinson, Usher, Alicia Keys and Brad Paisley who will perform at Obama’s galas on January 21st and a children’s concert on January 19th. More artists include Marc Anthony, Stevie Wonder, John Legend and the cast of “Glee.”

The concert and the two official inaugural balls are being held at the Washington Convention Center over the Martin Luther King holiday weekend. Beyonce, Kelly Clarkson and James Taylor were already announced to sing on January 21st.

More performers are Far East Movement, Mindless Behavior, Nick Cannon and gospel choir Soul Children of Chicago. Inaugural organizers aren’t saying yet which performances will be at which convention center event.

The Inaugural Ball, is expected to draw more than 35,000 people and will be held across all 700,000 square feet of the Washington Convention Center’s five exhibit halls, which four years ago held six separate balls.

The second event is the Commander In Chief’s Ball, a tradition started by President George W. Bush to honor the military with about 4,000 people. It will be held on the third-floor ballroom of the convention hall a mile from the White House. Tickets are free for invitees, including active-duty and reserve troops, Medal of Honor recipients and wounded warriors.
