By Andy Kellman Twin-sister act Nina Sky broke out with "Move Ya Body," based on Cordell "Scatta" Burrell's "Coolie Dance" rhythm. With its pattering bongos and synthetic handclaps, the backing track resembles a hopped-up version of Vanity 6's "Nasty Girl," and has spawned one release in the Greensleeves label's Rhythm Album series, in which a number of artists provide their own vocals over the same instrumental. (Prior to Nina Sky's own success with the track, the American audience might've recognized it from the remixed version of Elephant Man's "Jook Gal" that was nearly unavoidable on the video channels.) "Move Ya Body" also comes across like a slightly grown-up (if not as coyly charming) successor to Lumidee's "Diwali"-assisted "Never Leave You (Uh Oooh, Uh Oooh)," another infectious summer jam.
