In 2001, Andreas Heusser and Marc Rychener founded the interdisciplinary artist collective index based in Zurich. With index he organized a number of concert series, performances and festivals (e.g. "Festival der Künste" 2002, "Lyrik am Fluss" 2002–2005). In 2005, he initiated the international Artist-in-Residence-program Freiraum-Stipendium which is open to artists from all disciplines. In 2005, Andreas Heusser converted his artist studio at Elisabethenstrasse 14a into a cultural venue, where he staged 3–4 events per month until 2011, including a program cinema ("Kino im Atelier") and the concert and performance series "Mikro".
