Kenny Chesney has scheduled a new album, Hemingway's Whiskey, for a Sept. 28 release. It's his first album of new material since Lucky Old Sun in October 2008. The title track was written by Guy Clark, Ray Stephenson and Joe Leathers. "I knew I wanted the record to be something more, something that took what I do in my special projects and weaved it into what I do for the mainstream," Chesney says. "It takes a lot of energy and mental space to be on the road ... and I kind of felt like -- especially coming off of this second Greatest Hits -- this next record should be something that set the stage for the next phase of my music, the same way No Shoes, No Shirt, No Problems opened up the music I've made for the past eight years." Chesney released Greatest Hits II in 2009, then re-released it earlier this year with two bonus tracks.
