Even children’s movies seemed to be rubbing it in. There was the British singer Jessie Ware’s fourth album, “What’s Your Pleasure?”: It evoked peak-era disco’s mirror-ball largess, all for listeners whose idea of a “night out” had most likely been reduced to an extra trip to the grocery store. There was Steve McQueen’s intimate and lovely film “Lovers Rock,” in which you could watch a packed room of West London revelers sway and sing to Janet Kay’s reggae single “Silly Games” - lost in the moment, no social distancing necessary. So many striking musical moments from the past months have reminded us that we cannot, at the moment, be together.
