Based in Croatia, Unknown Festival is rapidly becoming one of Europe's hottest summer destinations.
Calling in favours from big name artists, Unknown regularly unveils exclusives which larger, more commercial, events fail to match.
Returning this summer, the festival is set to welcome a performance from London Grammar. Still frighteningly young, the trio hit the Top Ten last year with their debut album and toured across the globe.
Rapidly evolving as a live act, London Grammar will perform at Unknown alongside fellow new additions to the bill such as Clean Bandit and Moderat.
Jamie xx is due to appear at the Croatian event, while Nile Rodgers will bring the current incarnation of joyous disco troupe Chic to Unknown.
Tickets are on sale now.
Unknown runs between September 8th - 12th.
