ACCIDENT THEORY - OPEN AIR

As September comes to an end, and to close out a beautiful summer, Accident Theory is coming back strong under the Paris ring road at Kilomètre 25 for its final open air of the year.

After a memorable night last July, we’ve put together a line-up we’re particularly excited about, inviting some of the key figures of the French and international techno scene: Young Marco, Bambounou, Vanroose, Axel Blanc and a secret guest we can’t wait to reveal.

[YOUNG MARCO] NL
Dutch DJ and producer based in Amsterdam, Young Marco has become a prominent figure in the underground electronic scene thanks to his eclectic selections and his taste for rare and unexpected tracks.

Today, Young Marco is closely associated with Dekmantel, Amsterdam’s electronic music scene and a musical philosophy driven by curiosity: never limiting yourself to a single genre and always searching for the track nobody expects.

His biggest breakthrough came with his track “What You Say?”. Played during his famous Boiler Room set at Dekmantel, which has racked up hundreds of millions of views, the track quickly became a true phenomenon.

[BAMBOUNOU] FR
Parisian DJ and producer Bambounou began making a name for himself in the capital in the early 2010s.

After catching the attention of Modeselektor, he joined the legendary Berlin-based label 50Weapons.

Today, a true figure of the Parisian electronic scene, he performs in clubs and festivals all around the world, including Berghain/Panorama Bar, Circoloco Ibiza, Concrete and many more.

SURPRISEEEEE

[VANROOSE] FR
VANROOSE embodies an authentic and deep passion for music, driven by a strong musical culture and an instinctive need to bring people together.

Moving effortlessly between Prog-House and immersive Trance, her narrative sets, played straight from the heart, take audiences on a unique, powerful and deeply human sonic journey.

After making her mark with three All Night Long sets at the legendary Rex Club, she has taken her sound internationally, performing at iconic events and festivals such as Dimensions Festival, Nuits Sonores, Sunday Sunday in Mexico and Brunch Electronik.

[AXEL BLANC] FR
Born in Provence and based in Paris for several years, Axel moves between different electronic styles.

Having lived in various French and European cities, he draws inspiration from local club culture. For over a decade now, electronic music has become an obvious passion.

He has built his own universe, blending house, techno, UK and ghetto influences, trance, and many other more or less intense genres.

Over the years, both in France and internationally, from Copenhagen to Hamburg and Beirut, he has established himself at major events such as Tomorrowland and I Love Techno, as well as at clubs and festivals across France and abroad.
