Reading chamber music after a three hour opera is strangely like getting a good night of sleep and a cup of green tea. What a novel energy exchange. Happy to have a chamber-musically proactive visitor from the Berlin Philharmonic. Our library is a magical machine, extremely efficient and careful with their music. But hopefully the magic of Matthew, our viola visitor, will convince them to permit us to take some scores with us on the tour. No need for the backstage instant coffee. Brahms sextets will do.
