Studio Kalleinen is the collaborative base of artists Tellervo Kalleinen and Oliver Kochta-Kalleinen. In their artistic practice they attempt to merge the languages and approaches of a number of disciplines, such as game design, experimental education, dynamic facilitation and alternative economies. Tellervo and Oliver have developed a number of methods for a participatory art practice. They are known as the founders of the International Complaints Choir project. The artists are also founding members of YKON and Speechkaraoke.
