Patricia Kopatchinskaja - Schoenberg: Pierrot lunaire - The Guardian

As you’d expect from such an outstanding musician, her performance is impressively accurate, the realisation of the sprechgesang spot-on in rhythm and pitch, while the playing of the hand-picked ensemble around her is equally precise...But other aspects of her approach certainly won’t be to all tastes, for she certainly pushes the idea of what expressionism can be to its extremes.
