In 2006 Cheap Trick released Rockford, and for me it was the year’s biggest musical surprise. Here was a complete collection of brilliant pop and rock songs that fans had been waiting for since Dream Police. Subsequent records hinted of the band’s capabilities, but the results seemed to fall short of potential. Then as 30-year music vets, they didn’t just come back knocking on the door with Rockford, they kicked it down, square. It was a remarkable comeback, but could they carry through again?
