The German baritone Dietrich Fischer-Dieskau's 100th birthday falls on May 28. One of the most versatile singers of the last century – his operatic repertoire alone ranged from Gluck, Handel and Mozart via Verdi, Wagner and Richard Strauss to Berg, Busoni and Reimann – it's his devotion to song that remains his lasting legacy. To mark the anniversary of Fischer-Dieskau's birth, Gramophone's James Jolly spoke to song specialist and author of Schubert: The Complete Song Texts (Schirmer: 1988), Richard Wigmore.

They focused on Fischer-Dieskau's audio recordings of Schubert's greatest song-cycle Winterreise (1828) which include three with Gerald Moore, as well as versions with Klaus Billing, Hermann Reuter, Daniel Barenboim, Jörg Demus, Alfred Brendel, Murray Perahia and Maurizio Pollini.

In this week's episode, Editor Martin Cullingford met with the founder and Music Director of Bach Collegium Japan Masaaki Suzuki, along with the group's Principal Conductor Masato Suzuki, to talk about their new recording of Brahms's Ein deutsches Requiem, available now on BIS – as well as discussing Bach's St John Passion, which they had performed the day prior to the interview. The interview took place last year in, appropriately enough, London's Japan House.

In 2007, Yevgeny Sudbin released an album of music by Alexander Scriabin. Reviewing it in Gramophone, Bryce Morrison described it as a 'disc in a million'. Now, Sudbin has returned to the composer for his 25th recording for BIS, and offers a wide-ranging survey of music that includes two more of the piano sonatas.

James Jolly caught up with Yevgeny Sudbin recently to talk about his relationship with the composer and his unique musical world.
