The weather’s still a bit mediocre, but a reassuring sign that summer is drawing closer is that the festivals are starting to return. And as the name implies, few suit the sunny months better than Summerburst. This year they’ve secured one of the bookings that every Swedish festival was looking for, and bagged Justin Bieber for the main stage. The rest of the line-up tilts in a more EDM direction, with David Guetta, Deadmau5 and many more booked. The festival will take over Gärde on June 9 and 10.
