The DJ Marketing Bible will help you get things moving by either providing information on how to move out of your bedroom and into the scene or if you have already made it to clubs on how you can actually create solid foundations for your career.
There are 2 ways you can use the DJ Marketing Bible: firstly, the obvious way, reading it from start to finish so you can get all the information; some of which you might already know, some probably not with so many details. The other way is to go to specific chapters regarding the topics you feel you need extra boost at for instance when you are called to perform specific duties that you have forgotten how or simply you want to refresh your goldfish-like memory.
Bottom line? You are on the right track!
