This evening - following Boris Johnson's advice - I attended my firm's Christmas party, the first for two years.
Normally it's a dinner followed by a disco... I hang around until the coffee and mince pies have been cleared away and most people have wandered on to the dance floor, then I bugger off home.
This year, to my surprise, there was a live band (...and, incidentally, no coffee or mince pies). The band consisted of a singer, a drummer, a DJ (maybe also keyboard player?), a saxophonist and a trumpeter. No bass, no guitar. They played dance/disco stuff, some of which I recognised.
What got to me was how painful it was to listen to. I'm not sure if it was sheer volume or the harsh sound of the brass instruments, but it was like an ice pick in the ear. You couldn't talk over it, you couldn't even just listen because it was too uncomfortable. I went home even earlier than usual.
I don't really go to gigs any more but I don't remember the sound having this painful quality.
