In January 2020, already aware of how COVID-19 was impacting China and only weeks away from it colliding with Italy, Caroline and I were sitting third-row center at the Musical Instrument Museum for an inspiring performance by the Kronos Quartet. Here we are, four years later, and they have returned to Arizona for tonight’s performance at the Virginia G. Piper Theater in Scottsdale. Fortunately, there is no looming health scare on the horizon this evening, though the chaos wrought by populism and fear of our world going sideways is its own kind of pandemic. For two hours this evening, from the fourth row left of center, we are transported to this group’s brilliant modern interpretation of music that included what for us was an absolute first: the use of Pop Rocks popping in the mouths of two of the artists.
