In the Complaints Choir project the complaints of the choir members are transformed into an impressive choir song with the help of a local musician. The project is open for anybody, no earlier singing experience required. The complaints vary from small daily irritations to big global issues.
The concept was open sourced in 2006, and has been spreading around the globe since then.
The documentation of the choir performances from all around the world form a 4-channel video installation. The videos are shown one after another distributed over 4 walls.
