Besides composing, improvising and performing experimental music under the moniker hÄK I also produce music for other artists, as well as composing and designing sound for films, theatre and installations under my given name Bernd Norbert Würtz.

I have been lucky to be able to enjoy succesfull music collaborations with great people. Among them so far were Marc Teitler, Peter Challis, Ayu Okakita, VOOV and Sayoko Paris (Dosage). I was given the chance to work on interesting film-project swith great directors such as Dante Ariola, Yves Geleyn, Alexander Herzog, Peter Dörfler and Luc Besson and worked for institutions such as La Gaîté Lyrique in Paris and the Royal Opera House in London.
