Chicago punk-pop five-piece continues to grow, change

As suggested by its title, Shapeshifter, the sophomore album from Knuckle Puck, finds the Chicago-based pop-punk five-piece undergoing a bit of a personal metamorphosis. “I'm not who you remember,” singer Joe Taylor sneers on one tune. The musical evolution is more subtle, however, with the odd mellow cut (“Conduit”) interrupting the band's generally unrelenting forward momentum. After all, how would one gauge these internal shifts without occasionally pausing to take stock? (Safe Bet)
