With some distance from the brilliant thrashing of their early days, The Replacements offered a slick, polished sixth album. “Talent Show” is as straightforward of a pop song as the band ever made, with bouncy percussion and a catchy chorus; “They’re Blind” delivers a Replacements-style ballad, meaning the instruments are swelling and the emotion is raw. At the core of “Back to Back” is a surprising key shift wrapped in lush melodies and clean vocals.
