“We’re still the same band,” sings Brendon Urie on opener “We’re So Starving”. That’s hard to believe as Panic! At the Disco shed the angst and emo of their debut A Fever You Can’t Sweat Out for a beatific trip into lysergic '60s pop. “Nine In the Afternoon” exemplifies the immediate, sunny melodies, but the real pleasure emerges in repeated listens as you unpick the many layers of a record doused in strings, harmonies and relentless adventure.
