Self-isolation works well for me (or it should, if general societal anxiety didn’t creep in unbidden any time of the day). But what about those who create with others? I was reminded of a marvellous moment in Osaka last November. On a canal island, we sat, transported, with an “anyone can drop in” group of over a dozen musicians jamming on a jazz standard for … for seemingly forever. The session was led by a foppish stand-up bassist and a fast-fingered guitarist. Look at their joy! What of them now, holed up in tiny apartments? Will their souls shrivel up?
