His discography is large, and much of it has been reissued on CD or is available in download format. It includes the complete solo piano works and many of the
piano concertos of
Mozart, much of the piano music of
Brahms, and the complete
piano sonatas of
Schubert. He partnered with
Arthur Grumiaux in recording the Mozart music for piano and violin, and with
Rena Kyriakou in the complete piano music of
Chabrier. He performed and recorded piano duo and duet repertoire with his wife
Beatriz Klien and with his Graz contemporary
Alfred Brendel. He was much admired for his crystalline tone and projection of detail in his interpretations. His clarity of playing suited the music of Mozart and Schubert in particular. These qualities are also very evident in his Brahms recordings, where the dense textures of the writing can easily obscure the
musical argument. Critics continue to regard his complete Schubert sonatas as among the finest ever recorded, not least for their unique Viennese lilt and unaffected ease. == References ==
