Turbo Folk’s classic Ljubljana after-party venue is a good few kilometres from the city centre and rarely sees a single client before 02:00, but that’s all part of the fun. After the other venues have closed their doors, the deal is to pile into this dark underground cavern with its strange red lighting, pictures of naked women with bows and arrows on the walls and excruciatingly loud music and carry on with the Balkan-style party.
