"They bridge swashbuckling funk, soul, rock, and choogling blues. "Say You Don't Know Me" rides the roots rock & roll train with pumping upright piano, gospel horns, and Chuck Berry's trademark I-IV-V progression. "Heartbreak Street" weds vintage R&B to Memphis showband blues. "She's So Fine" commences with one of Cropper's trademark multi-string soul guitar vamps, but also channels swampy R&B and blues-rock as the horns, keys, and drums frame Reale's unruly vocal ... Fire It Up showcases Cropper's joyous brand of grit & groove with swagger aplenty".
