On ‘Perspectives 6’, Andreas Haefliger juxtaposes the Piano Sonatas of Beethoven with other composers, casting an enlightening glow on the works which one would not detect if played in isolation. Themes of humanity, nature and love run through a programme emphatically to be listened to rather than analysed intellectually.

Haefliger opens with Beethoven’s early Piano Sonata No.10, Op.14, then segues into two of Berio’s seldom heard encores, Erdenklavier and Wasserklavier. He emerges to perform Beethoven’s late Piano Sonata No.30, Op.109, followed by two more miniatures by Berio, Luftklavier and Feuerklavier. The album culminates with Schumann’s Fantasy in C major.
