Kenny Chesney has added four Las Vegas shows to his concert calendar in 2010. He will perform at the Joint at the Hard Rock Las Vegas on May 14-15, as well as July 2-3. The newly-expanded venue holds 4,000 people, and no seat is farther than 155 feet from the stage. As previously announced, Chesney is currently working on his next studio album, expected to be released in the fall. He will release a new single, "Ain't Back Yet," on Feb. 8. A new film, Kenny Chesney: Summer in 3-D, will be released nationally on April 21.
