Avicii’s place in the hearts of the dance-music community was illustrated at the 2018 edition of Tomorrowland when, a few weeks after his passing, a vast Swedish flag bearing the DJ’s face was unfurled across the crowd during friend and collaborator Nicky Romero’s MainStage performance. Three years earlier, the Swedish superstar had played the Belgian festival for the fifth time. Listening to his set now is a reminder of why he’s such a significant part of the history of the festival. Harnessing the power of hooks and chords, builds and drops, the music that he made, played, and remixed united hundreds of thousands of people in instant, enduring euphoria. In that sense, he perfectly embodied a festival that has long been celebrated for its spirit of togetherness and bringing dance music fans from every corner of the world to one spot each summer.
