The thrill of a trill

  Like that moment of hearing the first cuckoo in spring or the long awaited arrival of the first house martin, live music making is returning after the long sabbatical due to the pandemic.  It will be very good to resume this unique communal experience, which has been much missed by audiences and musicians alike.
