The Sans-Papiers Reception Centre Zurich (SPAZ) has been advising migrants without an official residence status for nine years and has been standing up for their rights and social integration. To mark its tenth anniversary, SPAZ organized two benefit concerts with the Die Vogelfreien choir on 13 and 15 March 2015 at the church of St. Jakob in Zurich-Aussersihl. Netcetera Cultura provided financial support to the benefit concert.
