"The ultimate NASCAR weekend just got even greater," said Ed Clark, president and general manager of Atlanta Motor Speedway. "Fans are getting great racing, great musical entertainment and up-close access like never before. This Labor Day celebration is much more than a race and we're going to great lengths to make the Pep Boys Auto 500 extra special for the fans."

Featuring classic country guitar and soulful singing enriched by three-part harmonies, Diamond Rio has blended a multitude of influences into a critically-acclaimed career spanning three decades. Fusing country, rock, strings and bluegrass, Diamond Rio has recorded nine number-one hits, including their debut single "Meet in the Middle," making Diamond Rio the first country group in history to reach number one with a debut single. Diamond Rio has recorded three platinum albums, received six Vocal Group of the Year awards from the Country Music Association and has been nominated for 13 Grammys.

Rising country star Jason Michael Carroll will take the stage before the Pep Boys Auto 500 armed with a sultry voice, recognizable hooks and looks to make young girls swoon. Carroll's 2006 debut album, Waitin' in the Country, produced three-consecutive country hits taking the album to the top spot on the charts. His most recent release, "Where I'm From" off Growing Up is Getting Old, has also been acclaimed as a hit.

Carroll's follow-up single, "Hurry Home," was released for radio play on June 29.
