Untold Festival is Romania's largest electronic music festival, held annually at Cluj Arena in Cluj-Napoca. The 2026 edition (the 11th, named UNTOLD ONE) ran August 6 to 9 with headliners including Sting, Martin Garrix, Marshmello, Kygo, The Chainsmokers, Steve Aoki, Flo Rida, and Lewis Capaldi across four stages and over 200 artists. The festival drew 427,000 attendees in 2024, 470,000 in 2025 (the 10th anniversary edition), and over 500,000 in 2026.

How Untold Festival Works

Untold takes over Cluj Arena and the surrounding city for four days and nights. The festival operates across four main stages: the Main Stage (EDM and pop headliners), the Galaxy Stage (house and techno), the Daydreaming Stage (melodic and organic electronic), and the Alchemy Stage (drum and bass, hip-hop, and live electronic). Stages also extend into Central Park and along the Somes Riverbank, creating a citywide festival experience.

Key operational details:

  1. Stages and Programming: The Main Stage hosts global EDM and pop headliners. The Galaxy Stage features underground house and techno acts like Carl Cox, Solomun, Jamie Jones, and Joseph Capriati. The Daydreaming Stage programs melodic and organic electronic acts. The Alchemy Stage books drum and bass, hip-hop, and live electronic crossover acts including Pendulum DJ Set, Denzel Curry, and Andy C.
  2. Ticketing: Four-day general admission passes start at around 875 Lei (approximately 175 euros). Under-25 passes start at 760 Lei (approximately 155 euros). VIP Mainstage passes start at 2,167 Lei (approximately 440 euros). Day tickets are available from 500 Lei (approximately 100 euros). Tickets sell through the official Untold website and iAbilet.
  3. Cashless System: Untold is a completely cashless festival. All purchases (food, drinks, merchandise) use a loaded wristband. You can top up online before the festival or at top-up stations on site. Any remaining balance is refundable after the festival.
  4. Accommodation: Cluj-Napoca sells out months in advance during Untold week. Book early. Nearby towns like Floresti and Apahida offer cheaper options but require rideshares or buses to reach the arena each day.

Why It Matters for Independent Artists

Untold draws over 400,000 attendees across four days, making it one of the largest festivals in Europe by attendance. A booking here puts you in front of a massive international crowd drawn from across Romania, Europe, and beyond. The festival's multiple stages mean booking opportunities exist beyond the Main Stage, particularly on the Alchemy and Daydreaming stages which program niche genres and emerging acts.

The strategy for getting booked:

  1. Target the Alchemy or Daydreaming stages if you produce drum and bass, hip-hop, or melodic electronic music. These stages book emerging acts alongside established names.
  2. Build a following in Eastern Europe. Untold bookers track artists who perform well at regional Romanian and Eastern European venues and festivals.
  3. Work with a booking agent who has relationships with the Untold Universe team. Most slots are filled through agent submissions.
  4. Use our Streaming Royalty Calculator to track your streaming growth, as festival bookers look at streaming data when evaluating emerging acts.
