Broadcasting the opening concert is the brilliant Boiler Room, whose Gabriel Szatan says: "Last year's show from Dimensions' Opening Concert was, quite simply, one of the finest all-round sessions in Boiler Room's history. Nils Frahm and Darkside were both jaw-dropping bookends, and Caribou's entire set felt like a coronation for one of the best electronic artists of the era making a thoroughly deserved mainstream breakthrough. It is with enormous pleasure that we're returning to that gorgeous amphitheatre in Pula for more of the same in 2015.”
