“Traveler, there is no road. You make your own path as you walk.” Inscribed on the wall of a Spanish monastery, these words were discovered by Luigi Nono in the 1980s and became a kind of motto for his late works. The search for an unattainable music of the future also infuses his penultimate score La lontananza nostalgica utopica futura, composed in 1988–9. Carolin Widmann and the SWR Experimentalstudio bring the piece to the Pierre Boulez Saal. Widmann complements Nono’s meditation on space and sound with works from the 18th and 21st centuries by Telemann, George Benjamin, and Swiss composer Helena Winkelman.
