In the framework of Zwijgstil Q-O2 and De Munt feature Finding Song Home, the sonic bike opera made for Brussels by Kaffe Matthews. It explores the injustices of birthright and the power of nations governments to enable or prevent the free movement of its citizens. Through meeting and sharing with often illegal non-European Brussels immigrants, Matthews has gathered a mass of their stories which, intimately told through the voices of the tellers, create a multi-threaded libretto to be revealed by audience cycling the GPS linked sonic bikes through and beyond Brussels centre.
