Anyway...so they direct me to their myspace site to hear their music. Quality matters folks. If you can't get a good sound from myspace, send me a demo cd.
Some bands contact us over and over and over. I get tired of responding to the same ones sometimes. For the most part though, I have to give a lot of bands here credit...they are very professional in their contacts.
My advice boils down to this
1 - Know the venue. Do they book all genres? Or do they do just metal? Or country? etc.
2 - If directing them to a website to hear your sound, make sure its good. If not, send them a cd. If its still not good, practice some more.

3 - Email or message online such as myspace is usually a good way to contact them...the first time. If you don't hear anything, call. Don't keep sending messages. When calling, don't call during busy times such as a night when they have another band booked.
4 - If you really want to make contact, call and find out when the person you need to speak with is available and stop in. That face to face is great. Not only do you meet us, we meet you and you get to see the place. You would then have the opportunity to see what equipment you may or may not want to bring.
Another tip I can throw in there....if you are playing nearby and the fans mention our place...tell them to speak to us about it! We love to hear from your fans as much as you do. You get 20 people coming in tell us you are a great band is so much better than you sending us 20 emails stating that.
If you want to come back, some things to consider...its always nice when the bands take an interest in our place. They don't leave a bunch of trash behind where they were set up at...don't bring drinks in from the outside unless you are really into something we don't carry (non-alcoholic types of course). We don't let our customers do that...to me its rude for band members to bring in gatorade when they could help us out by buying it from us...or red bull. Let our customers know that you are into them...they are the ones that are paying you and ringing in our register. Socialize with them...they will love you for it and will tell us how great you were to them....it really does work. Plus, you socialize with them, they tend to buy your drinks. Oh speaking of drinks, when a venue gives you drink tickets, use them yourself. Don't give them to the customers. We count on them paying for their own drinks.
Ok...don't know why I felt the need to type this today. Guess it was the crappy myspace site I was just on.
