About Ō Lac
Ō Lac Festival: Electronic Music by the Lake
Since 2023, the Ō Lac Festival has established itself as a must-attend event on the electronic music scene in Auvergne-Rhône-Alpes. Located on the shores of Lac d'Aiguille in Châteauneuf-sur-Isère, in the heart of the Valence Romans agglomeration, this festival takes advantage of an exceptional natural setting to offer a unique musical and visual experience.
A Signature Floating Stage
The floating stage of the Ō Lac Festival has become the festival's emblem. Set up on the waters of Lac d'Aiguille, it offers a striking visual spectacle, with artists performing literally on the water, surrounded by light shows that reflect on the lake's surface. This unique staging creates a magical and immersive atmosphere that sets Ō Lac apart from all other electro festivals in the region.
An International Electro Lineup
For three days, the Ō Lac Festival features the best international electronic music artists. Among the headliners who have graced the floating stage: The Avener and Jimmy Sax, Kungs, Purple Disco Machine, Claptone, Boris Way, Hugel, Vladimir Cauchemar, and many others. The lineup skillfully blends house, deep house, electro-pop, and tech house, offering an eclectic musical journey that appeals to both electronic music enthusiasts and the curious.
An Exceptional Natural Setting
The Ō Lac site, located at 430 Route du Lac in Châteauneuf-sur-Isère, benefits from a privileged natural environment on the edge of Lac d'Aiguille. The former Palais des Congrès Sud Rhône-Alpes has been transformed into a unique event space, combining outdoor areas by the water with modern infrastructure. The green setting and proximity to the water create an atmosphere of relaxation and celebration that contrasts with the usual industrial sites of electro festivals.
A Thriving Festival
In just a few editions, the Ō Lac Festival has brought together over 8,000 festival-goers over three days, confirming the enthusiasm for this new musical event. Driven by the Émotions association and the Ō Lac team, the festival continues to grow while preserving the intimate spirit and quality of experience that are its strengths. The ambition is to become one of the reference electro festivals in the Rhône valley.
