Audio Obscura has announced the return of its flagship festival to the UNESCO World Heritage site Van Nelle Factory in Rotterdam for 2026. Billed as a “temporary cultural intervention” rather than a traditional music festival, the event aims to merge electronic music with industrial architecture. Several collaborative sets have been confirmed, including DJ Gigola b2b Chloé Caillet, Obskür b2b Luuk van Dijk, and Jöella Jackson b2b Rayzir. In line with this philosophy, a portion of the proceeds from the 2026 festival will be donated directly to the preservation of the Van Nelle Factory as a UNESCO World Heritage site. The Rotterdam festival serves as a foundation for the organisation’s philosophy, specifically designed to interact with the city’s raw industrial heritage.
