On his 21st album, Kenny Chesney sounds newly energized, his sturdy croon nestling into stories about love, loss, and letting loose. “Carry On” feels like a future staple for Chesney’s marathon concerts, its story of a raucous bar’s fascinating mainstay feeling in line with story songs like “Boston.” “Burn My Boat” hints that Chesney might be willing to give up the high seas if the right person enters his life. “Talkin’ Dirt” is a honky-tonk-ready stomp that takes on small-town gossip while subtly nodding at his own time spent under fame’s microscope, while the swaying ballad “Sad Casino” shows how a slot machine’s flashing lights can illuminate post-breakup despair. Duets with newly minted superstar Megan Moroney, upstart singer-songwriter Lily Meola, and pop-folkie Colbie Caillat add to the album’s expansive feel, their voices braiding with Chesney’s resonant instrument as he muses on romance.
