I have been on something of a musical diet this season, and the concerts I have attended have been few, including piano recitals, which have proven nonetheless wide in range, with newcomers to the city as well as the quintessential New Yorker, Richard Goode, and the continuation of Angela Hewitt’s transcendent Bach Odyssey, which has been the lodestar of my musical life for some years now. All have had something memorable to offer, especially Ms. Hewitt, and I have very little to grumble about, unless it is the smartphone-addicted audience at Daniel Ciobanu’s recital, who seemed to have no idea of what a classical concert entails in terms of how to enjoy the music and how to allow others to enjoy it as well.
