In late May of 2009 – during recording sessions for a disc of Mozart piano sonatas (later to become Volume 1) – my producer Robina Young and I found ourselves outside for a coffee break. Robina asked, quite casually, what I fancied tackling next, to which I promptly replied, what about all of Mozart’s keyboard music? It was a wild shot in the dark, ambitious and a little mad perhaps, and I never thought she would agree, but to my surprise, her response was positive. What followed was a seven-year period during which we recorded nine CDs in the luxurious acoustic of Air Studios in North London, all devoted to the mature keyboard music of Mozart. It is, I feel, music that is sometimes overlooked in favour of Mozart’s better-known masterpieces like the mature operas, piano concertos and string quintets. But make no mistake: this is music of great insight, character, beauty and innovation, and I am deeply grateful to Harmonia Mundi and Robina Young for their trust in me, and for the opportunity to have immersed myself so fully in this remarkable repertoire. Now these nine volumes have been collected in one beautiful box set.
