For most of Blake’s fourth album, longtime collaborator Bobby Braddock gives way to hitmaking producers Paul Worley and Brent Rowan. The result is a more muscular, radio-ready sound that lends Blake an extra dose of modernity, but also subjects him to a few Nashville-centric annoyances—for example, the slathering on of those overbearing, overly perfect background vocals to which Music Row seems inexplicably attached. But Pure BS is kept afloat by Blake’s engaging personality, infectious humor and a few canny song choices— especially Chris Knight’s masterful “It Ain’t Easy Bein’ Me.”
