Pop fan Guy Lawrence, 21, felt dance-music nirvana when he heard Joy Orbison's 2009 dubstep head-fuck, "Hyph Mngo." With brother Howard, 18, he's heir to the tradition of the Chemical Brothers, Basement Jaxx and Daft Punk: marquee EDM duos as devoted to vocal-driven songcraft as they are to beatmaking. The pair's debut is a modest masterpiece of production finesse, rooted in house but borrowing from hip-hop, dubstep and other club mutations. Listen to AlunaGeorge's warped Cockney flourishes on the buoyant "White Noise," or the voicelike keyboard pulses on the triumphant deep-house jam "Defeated No More." These bros know how even subtle tweaks can turn the pedestrian ecstatic.
