There's serious pop pedigree behind this debut album from last year's X Factor winners. Rihanna hitmaker Ester Dean is among the writing team, while a cameo from TLC's T-Boz provides an endorsement from girl groups past. The results are predictably slick and well stocked with clever production touches: processed guitar, strings and robotic vocals tangle effectively on Red Planet, Madhouse adapts elements of Florence-style melodrama. But such an efficient compendium of current pop influences is a little underwhelmng; nothing here sets out to redefine the girl group sound, as Little Mix's talent show forebears Girls Aloud did a decade ago.
