Performer: Joonas Ahonen

Klangforum Wien finishes a far-reaching excursion into the boldest realms of modern music with a flourish.

Schoenberg's modernist masterpiece gets lost in a fog of words and feral newsprint at the Southbank Centre's Purcell Room. 

The Edinburgh rain was the third performer in this concert, and unfortunately detracted from the two on the billing.
