Swedish soprano Camilla Tilling’s latest recital offers listeners a musical portrait of a changing city. At the turn of the 20th century Vienna was a city of collisions and contrasts, pulled between conservatism and experimentation, rigid class divisions and liberal intellectualism, the splendour of the Ringstrasse and the squalor of the slums. The result was the “Jugendstil” (Youth Style), which took the city from decorative Art Nouveau innocence to the cooler, geometric abstraction of modernism, from peace to war.
