For her new recording, entitled Or (light), cellist Sonia Wieder-Atherton has devised a two-part narrative, "like freeze frames, like incursions into time": first, Couperin's Les leçons de ténèbres or the Lamentations of the Prophet Jeremiah. Prophecies are the time before. Before destruction and tears: "We hear the song of the prophet lamenting, but the possibility that this will not happen still exists."

Then comes "our time": "With his dramatic force, Vivaldi confronts us with our present. He says, 'This is now.'" Sonia has chosen several excerpts from operas as well as two violin concertos. She transcribed most of the pieces in this programme for solo cello or two cellos, two voices that she plays herself. She also imagined bridges to other lights, those of Mahut's percussion and Marius Atherton's electric guitar and MS20 synthesiser.
