You've booked a show!  Congratulations on this accomplishment!  Now, there are a few simple things that need to be done in order to assure this experience turns out good, not only for you, but, also for the crowd.

First of all, get your artists confirmed.  Having your artists confirmed early on is integral in having a successful show.  Once your artists are confirmed, it's much easier to set a line up and make fliers for the show.  Which leads us to...

Second... MAKE FLIERS FOR YOUR SHOW.  Yes, Myspace is a great place, and people say facebook is too.  Chances are, the majority of your friends list is not local, or, composed of people who will drive to see your show.  Thus, you must make your show known to people in the area who WILL drive to see your show.

Third, promote your show on radio.  Now, it may not seem cost effective, but in reality, many stations are willing to support local artists by mentioning their show on the air, and allowing them to plug their show in a live appearance.  This is best done on stations that reach local audiences, again, not internet audiences.

Fourth, start your show on time.  When someone such as myself walks into the club or bar where your show is being put on and there is no music playing, I, or someone like me, am/is most likely going to just turn around and leave.  Especially if it isn't the first time.

Fifth, set a cover charge.  Make it reasonable.  No one is going to go see your local group for $20.  Very few people will go see your show of locals for $10.  It may even be hard to get people to go in for $5.  A good range is between $3 and $5.  For bar establishments that will allow show attendees between the ages of 18 and 21, have them pay a higher cover as they will not be buying alcoholic beverages.  While a free show is and can be a great thing, for some reason people view things such as free shows as inferior.  They think that if the show is free, it must be because the show isn't worth paying to see.  Possibly the only exception to this is if it is an outdoor show.

Finally, by doing the above steps, you are likely put on a successful show!  Skipping any one of the steps, however, can leave your venue empty.  An empty venue makes for a poor show. Regardless if someone is trying to record it for tv and they feel that a crowd would ruin the sound.

Now go out there and book a show! But, remember, with no promotion comes no attendence.  No attendence makes for a bad reputation.
