Either I leave without seeing all the acts I've paid to see or I leave at stupid o'clock and I've to to get up the next morning.
Okay if the gig is a spectacular, something like AC/DC or Leonard Cohen or even the mighty Just Joans, then I don't mind it running late, its a once in a life time show, but on the whole gigs running late pisses me off mightily.
I've been to more concerts than most people, whether this makes me an authority on gigs very much depends on your definition of 'authority' and also on 'makes me', maybe 'gigs' too. Anyhoo I know when a show has pissed me off and I know the usual cause.
Its up to the promoter or the sound guy or the stage manager, they've got to know when to tell bands to hurry up, when to cut their set short, when to get off stage. It takes someone to write up a sheet of stage times, and somehow stick to it.
Sure the bands on stage don't give much of a shit, they're to play their songs and get paid, how long it takes don't figure much in their experience.
Some acts are prima donnas who assume that cos the first band over ran and instead of a brisk three-song set they played five songs extended long play versions with player introductions and solos, dedications, and a brief poetry interval, this means that all the bands are entitled to overrun.
It just pisses off the folk in the crowd who've stumped up the money and come along, the paying customers, the fans, the faithful. It makes us hate you and your music. It leaves a bitter taste in the mouth so next time we see your name in the gig listings we don't think oh I love those guys and their interesting choice of cover versions that made up question our prejudices about the type of music, but makes us think oh for fucks sake, those fucks made us miss our favourite band, fall asleep whilst driving home and again whilst driving home from work the next day.
It shows contempt to the crowd and contempt to the other bands on the bill.
Look the music and the songs are about 50% of the gig experience, the other 50% is the price to get in, the folk talking over the music, the price of drinks and how disorganised it is. Look if you mix a bucket of ice cream with a bucket of dog shit, the result is going to taste mostly of dog shit.
