I understand that it is a package including a demo, but I am not certain about what else goes into one. Please send me information on where I can find specific answers on what is in a press kit and why those items are to be included. It is like telling someone what the best recipe for tuna salad is. Personally, I do not like sliced gherkins in mine. Some like raisins, some think carrots belong in the mix.
Demos are similar.
The usual demo package can be, and usually is overdone. Many people include the promotional equivalent of gherkins, raisins, carrots and even chocolate chips in their demo presentations. The main ingredient, however, is great musical material, not the packaging material. Not the packages with important looking labels that artists believe will be opened first. Thus, the great gold metal flaked box goes to waste as someone's assistant curses you for messing up their desk.
