New music: Alex Winston - Sister Wife

You may have read about Detroit-based singer Alex Winston in one of the many "big in 2011" features that are doing the rounds. And while she's not as hugely hyped as Jessie J, there's a still high level of expectation. Sister Wife – the first taster from her forthcoming EP of the same name, produced by the Knocks – continues her rich vein of chart-friendly pop with an edge that started with last year's Choice Notes, a song so laden with plinky-ponk pianos that it wound up soundtracking an escapist car advert. Over airy, intricately arranged drums and distinctive vocals, Sister Wife seems sickly sweet on the surface but, like all good pop, hides a dark core. The Sister Wife EP is available to download on 7 February (with a physical release on 4 March). The Sister Wife single can be downloaded for free here .
