Is it really possible for a single performance to completely change your view of a piece of music – even a work that you must have heard hundreds of times? In this line of work, it happens with regularity. There I was, thinking I knew Schubert’s Impromptus backwards, having listened to more recordings of the pieces than I care to admit, and suddenly Alexei Lubimov came along a few years ago with a couple of restored early 19th-century pianos and tranformed their aural landscape. I haven’t heard them in the same light again. From the opening bars of Isabelle Faust’s new recording of Mendelssohn’s Violin Concerto, you get a sense of its chamber qualities – the soloist much more a part of the whole than pitted against the symphony orchestra. Gut strings make Faust’s violin a good deal quieter than we’re used to on a Romantic concerto recording, yet the Freiburg Baroque Orchestra responds with playing of sublime delicacy. Turn to p26 to learn exactly what went into making their disc such a success. You could, of course, stream it on any number of websites and apps – and on p40 we present a guide to the best streaming services. Almost all of them are constantly evolving (or sadly closing), so it may well be a subject we’ll return to in the near future. However, we believe the time may be right to dip your toes in. But not without reading our sage advice, of course!
