Three young singers and a world-famous string quartet find themselves in a deserted room. They are wearing the old costumes from Guy Cassiers' Proust series for RoTheater. They perform a beautiful musical work entitled 'Prayer of the Heart' (1999) by the British composer John Tavener, an excerpt from 'Orpheus in the Underworld', first performed at this year's Opera Days festival in Rotterdam. Orpheus is torn apart by sorrow and guilt. Eurydice appears as both love and death. By means of a mantra, which the singers repeat in various languages, Orpheus manages to unite and accept love and death.
