Beneath the slick production and saccharine songwriting that dominate Nothing But Love lies the unmistakable talent of two gifted siblings, who imbue even the most insipid material with sincerity. Sixteen-year-old Amanda sweetly nails the tear-jerking mother-and-daughter ballad 26 Cents and wrings real emotion out of the corny forbidden-love saga of Williamstown, although she's poorly served by the forced twang of Back on My Feet. Younger brother Tyler, a mere 14, adeptly delivers the countrified puppy love of Don't I Have a Heart and the vaguely ‘80s-sounding reverb-filled rocker Then There's You. Father Steve rounds out the trio, chipping in on the ubiquitous, tightly meshed harmonies and co-writing (with help from Music City pros) most of this debut's 11 songs. If the Wilkinson kids escape the Nashville studio knob-twirlers and put their limber voices in the hands of more-sophisticated songwriters, their next CD could be as remarkable as this one is bland.
