Details: Each of Beethoven's piano concertos is a world unto itself, gripping and moving in it's own way and for it's own set of reasons. But even in this company, the Concerto no. 4 stands apart. It's opening phrase, inward-facing and played by the piano alone, immediately establishes that it is a work without precedent or parallel. It is full of contradiction - poetic and grand in equal measure - and makes an indelible impression on the listener. Many pianists will say it is the Beethoven concerto they love most; I am among them. It is fitting that this work inspired the strangest, most surreal companion piece of the Beethoven/5 project: Salvatore Sciarrino's Il Sogno di Stradella. Described by the composer as a concerto "not only of sounds but of resonances, near and distant," the work toggles back and forth between the composer's own spectral language, and one which evokes the 19th century. It is impossible to describe and utterly compelling. Recording these works live but without audience with the Swedish Radio Symphony Orchestra in the midst of the Covid-19 pandemic was an intensely intimate experience. It is extremely gratifying to finally share these performances with music-lovers not just in Stockholm, but throughout the world. (Jonathan Biss)
