At 83, Paul McCartney still hasn’t slowed down. His recent stadium tour was sold out. His elegiac performance of “Hello, Goodbye” was a perfect farewell during the final episode of The Late Show with Stephen Colbert. And his first solo album in five years is a candid and introspective ode to those early years in postwar Liverpool. The album offers vignettes of the Beatles before Beatlemania, highlighting stories of how the singer hitchhiked across the U.K. alongside John Lennon and George Harrison. “It was a good way to get to know you”—he sings on the track “Down South”—“Before we learned to twist and shout.” Another track marks the first duet sung by McCartney and bandmate Ringo Starr. The project is steeped in nostalgia, but carried by the definitive rock-and-roll sound the British singer established many decades ago. —Maggie Turner
