Review: This is what you'd call smart and sassy. Sat somewhere between intelligent deep house and contemporary tech house, this latest single from Leisuregroove and Rustem Rustem's Electronic Youth outfit features smooth lead vocals from veteran British R&B singer Kele Le Roc. Her vocals fit snugly with a retro-futurist groove that evokes memories of dancing like crazy to bleep-heavy US house cuts, sometime in the late 1990s. It's a good look, and arguably the duo's best single since joining forces in September 2011. It should win them an army of new fans.
