This is a brilliant idea for a CD. Composed within a time-frame of 11 years (1917-28), at a similar geographical distance from the main cosmopolitan centres of music, and with similar stylistic overlaps between late Romanticism and modernism, these two pairs of quartets make for genuinely illuminating comparison.

My late, lamented colleague, Michael Oliver, would have exulted at the prospect of reviewing this hardly-ever-heard example of verismo, a genre (like so many others) of which he made a speciality. Ponchielli’s last opera appears never to have been recorded before, and has received few performances, even in Italy, after its comparatively successful première at La Scala in 1885.

This live recording of Strauss’s Metamorphosen and Beethoven’s Eroica Symphony marks the birth on record of the ‘Sinfonia Grange au Lac’, an orchestra created in July 2018 on the occasion of the Rencontres Musicales d’Évian, the prestigious festival created by Mstislav Rostropovich in 1985 and revived since 2014. A musical ambassador intended to promote the excellence of its parent festival worldwide, the Sinfonia Grange au Lac consists of musicians from leading European orchestras (in Amsterdam, Berlin, Frankfurt, Leipzig, London, Lucerne, Munich, Paris, Salzburg, Valencia and Vienna) as well as existing groups such as the Trio Karénine and the Quatuor Ébène. And it was a stroke of genius to manage to secure the services of Esa-Pekka Salonen.

The transcription and arrangement of musical works was common practice in the 18th century. Such illustrious musicians as François Couperin and Jean-Philippe Rameau left remarkable "manners" and examples of transcriptions for one or two harpsichords. In his preface to L'Apothéose de Lulli, published in 1725, François Couperin explains how his music for two dessus (treble parts) and bass can be played on two harpsichords: "I perform them very successfully with my family and pupils with the first dessus and the bass played on one harpsichord, and the second dessus and the same bass-line on another, in unison."
