The cycle "House of Call" unites invocations, prayers, poems, and songs composed for a large orchestra. Heiner Goebbels integrated recordings of voices and sounds from various parts of the world, which he had collected through travels, research, and chance encounters. The composition engages with the history, complexity, originality, and resonance of these recordings. In this secular responsory, the orchestra assumes the role of accompanist: it supports the voices, enters into dialogue with them, responds, and presents them with tasks.
