The correct way to deal with poor promoters who pretend they are awesome....
i have given some serious thought to working with you in the near future. here are my thoughts based on discussions so far.
"...if you have never stepped into X, X, X, X, X, X on a X night then you would not have heard of us but we have been around for years..."
This statement leads me to believe that you don't do that much promotion. I pass some of those venues on a regular basis and I pay attention to what's on and i still don't know about your night. This doesnt fill me with confidence.
My question about why you contacted us was more about why you would ask us to play your nights. I found your reply slightly condescending.
"cross pollenating" fanbases sounds like a made up faux industry term. I looked at your venue sizes, at the ticket costs, and the payment scaling based on ticket sales. We've already established that you don't promote your own nights much so it sounds like you rely on bands promoting themselves hard, going out and selling tickets, dealing with the money, keeping track of whats sold, putting in the legwork, flyering, whatever... in order to collect decent amount of money. once that amount is gathered you take your percentage. from what i worked out using venue sizes and some arbitary figure, you take roughly 60% of the total bands takings. which obviously varies night to night.
so you're taking 60% of the money that the bands effort generated, you don't do much promotion and by your own admission id have to be inside one of your nights to find out about it. so it seems like you're asking bands to write music, record music, perform music, be salesmen, promoters, bring people to your night, their fans, their friends, who spend money at the bar get merry then leave, and you take a nice little wedge for doing what? I promote my bands shows as much as i can anyway, but im not into people taking advantage of my own work.
sounds like you want bands to go shopping, cook the food, put the food infront of you, but you wont let us sit down and eat with you? without bands you're nothing but a good idea, so stay in your place.
EDIT: I love good promoters. this is for bad ones. i emailed this to one such company
