classical musicians would not last ten minutes in a public bar ,most people have gone there to drink alcohol, generally a lot of roaring, scoving, acting the goat, fools playing pool,
I've heard the cellist Matthew Barley "last" about an hour and a half playing mostly-contemporary music in a pub. But it was to an audience that knew how to pay attention. Not the first time I'd heard art music performers doing that sort of gig.
Is there any point at all in playing any kind of music to a roomful of shouty drunks who don't want to listen?
