We went back to the Wigmore Hall for the first time for many moons to hear Pavel Kolesnikov play Mozart and Chopin. I had deluded myself that listening to music on Spotify was an adequate substitute for the real thing – better at least than looking at digital images of pictures online – but I was quite wrong: most of all in the quality of sound for which a recording is ultimately a nearly, but not totally pure substitute; and the sense of performance – the languid way he played Mozart, the fortissimo of the final Chopin, even the occasional coughing towards the end was faintly reassuring that the normality of real experience is coming back again.
