Over the six distinctive tracks on Forbidden Islands, Madrid duo Uanamani defines their broad and multi-faceted vision of techno and ambient. The two genres become one in Derk & Iterbio’s hands. Propulsive rhythms surge forward, peak and disintegrate into plumes of heady fog. Float with the weightless two openers, drill deep into dubwise territory with “Punatori,” soar with club cut “Poveglia,” then ride out the smooth descent.
