Swedish House Mafia previewed the next installment ‘Atom’ from Nari & Milani out in March on Steve Angello’s SIZE imprint. The premiere revelation was during the Swedish House Mafia set at the Ultra Music Festival last Saturday. The Italian producers have returned to Size Records after their excellent debut with ‘Kendo’. ‘Atom’ boasts powerful, high-pitched synth lines to preceed a throbbing drop indicating their excellent production in this Size signing.
