The Chainsmokers are the latest addition to this year's EXIT Festival lineup, joining the likes of The Cure, Skepta and Carl Cox in Serbia this July.
The duo have risen to immense fame in the past few years, picking up 24 awards, including a Grammy, three MTV awards and seven Billboards.
2019 will also see the pair release their eagerly anticipated third studio album, further cementing their place amongst dance music's elite.
EXIT Festival emerged from a huge student protest back in 2000, evolving to be crowned Europe's Best Major Music Festival twice in the last five years.
Each year, the festival showcases a diverse music program that covers rock to punk, hip-hop, and the best electronic music across over 40 stages inside the fort's moats, trenches and even tunnels.
Tickets, accommodation and extras to EXIT Festival 2019 are available here.
