Dwight Yoakam, Usher, Sheryl Crow and Al Green will play the Mercedes-Benz Summer Concert series, the annual outdoor concert series that airs on "The Tonight Show with Jay Leno" on NBC.

Yoakam kicks off the 11-show series with a performance on May 15. It marks his 24th appearance on the "Tonight Show" -- the most for any performer and just besting the previous record holder, Lyle Lovett.

Each band in the concert series will receive additional play on NBC.com where interviews and photos will be posted, as well as a second song performance by the artist.

The events are filmed at the NBC Studio midway in Burbank. Additional artists will be announced throughout the summer.
