On 5 May 2012 the world premiere of the "Requiem for Auschwitz," by composer Roger Moreno Rathgeb, was performed at the Nieuwe Kerk in Amsterdam by The Roma and Sinti Philharmoniker directed by Riccardo M Sahiti. The Philharmoniker is a pan-European orchestra of Roma and Sinto musicians generally employed by other classical orchestras; it is focused on the contribution of Roma culture to classical music. Dutch-Swiss Sinto Moreno Rathgeb wrote his requiem for all victims of Auschwitz and Nazi terror. The occasion of the premiere was coupled to a conference, "Roma between Past and Future." The requiem has since been performed in Tilburg, Prague, Budapest, Frankfurt, Cracow, and Berlin.
