It’s a simple trick, but one that young music-maker Gloomy pulls off well on “Roller Girl.” It’s the old “upbeat meets crushing” formula, of mashing something sunny against something not so bright. On “Roller Girl,” the sunshine comes courtesy of Gloomy’s vocals which practically skip, even when she starts to adopt a cadence bringing to mind The Knife’s Karin Dreijer Andersson late in the song (check the way she says “do”). Yet rubbing right up against her cheery melodies are the backing electronics, an aggressive array of steel-cold sounds one would expect from House Of Tapes or, like, Clipse. Or The Knife.
