Denmark's Roskilde festival has been attracting music fans of all ages for close to 50 years. This year's sold-out event—which begins today—will attract over 130,000 guests. The seven-day festival also may be Europe's best kept party secret. With this year's headliners including Foo Fighters, Arcade Fire, The Weeknd, and Solange, among other heavy-hitters, fans seemed more than prepared to jam all day long, before the event even started. Photographer Matías Altbach was on the grounds as the festival was just getting started to confirm this Roskilde is one hell of a good time. Experience it all below.
