Olof Dreijer

Olof Björn Dreijer is a Swedish producer and DJ from Nacka who began his solo electronic music career in 2021. Born November 27, 1981, Dreijer is one half of the electronica duo The Knife, formed with his sibling Karin Dreijer. He has released music under the aliases Oni Ayhun and DJ Coolof, accumulating seven solo releases since October 2021.

Dreijer's solo work spans bass house, breakbeat, and raw techno, with releases appearing on respected labels including Dekmantel, Hessle Audio, Phantasy Sound, and Melodies International.
