Olof Dreijer (he/him), Swedish music producer and member of the duo The Knife, is a key figure in the international electronic scene.

Active for over two decades, he blends club culture, sonic experimentation and unconventional performance. As Oni Ayhun, he explored queer aesthetics and radical sounds, performing at venues such as Berghain and Liquid Room Tokyo.

​

He has produced and remixed artists including Fever Ray, Houeida Hedfi, Planningtorock, Zhala and Nine Inch Nails. His ever-evolving dj sets move between techno, melodic house, baile funk and batida.

At Electropark 2025, he brings a dense and visionary set — a musical journey shaped by fluid, collective and liberating sound explorations.
