For the first time, NBC will offer one of "Today's" summer concerts on iTunes. The morning show’s Friday, August 25, John Mayer live concert will be made available in its entirety – along with some special behind-the scenes footage – as part of "NBC News On Stage," which debuts on iTunes Tuesday, August 29.

John Mayer's performance on "Today" precedes the release of “Continuum,” the Grammy-winning artist's first new studio album in two years. The album's first single, "Waiting On The World To Change" has been an iTunes Top Ten mainstay since it became available in early July. “Continuum” will be available for pre-order on iTunes beginning August 22 and released in stores and online on Tuesday, September 12.

In addition to the John Mayer concert, the new "NBC News On Stage" section on iTunes will include memorable, extended conversations with some of the biggest legends of the music world – rare and exclusive interviews from the NBC News archives. Each interview will also be accompanied by unique bonus material.
