Returning to the summer concert series are Chris Brown and Justin Bieber. Last summer, Brown drew an estimated 18-20,000 people to Rockefeller Center, the biggest Today show crowd ever (beating out Bieber's enormous crowd in 2010).

The concert series will also feature newcomers Hot Chelle Rae in their first morning show concert, and two Today show favorites, Maroon 5 and Train.

For the country lovers in New York City, Kenny Chesney, The Band Perry and The Zac Brown Band will all be headlining free Today concerts this summer.

Something new this year: Today is partnering with Pandora to extend the concert series beyond the Plaza and into the web. Pandora will create three Today Summer Concert Series stations: NBC Today Rock, NBC Today Country and NBC Today Pop, featuring each of the artists appearing in the series throughout the summer.
