"Country-rock charm from Kenny Chesney - As the leader of what he's dubbed "No Shoes Nation," the laid-back country megastar Kenny Chesney doesn't really need to release albums. His shows, including the sold-out gigs at Gillette Stadium that have become a summertime tradition, are already chock-full of tracks from a catalog that spans all the way back to 1994. He could probably please crowds just by continuing to run through his twang-tinged hits, which triangulate the beach, the heartland, and the road to create a space in country music that he owns pretty much free and clear.But Chesney isn't one to rest on his laurels, and his 17th album, "Cosmic Hallelujah," bears that out".
