Tao Te DJ Chapter 2
Under heaven all can see beauty as beauty only because there is ugliness. All can know good as good only because there is evil. Therefore having and not having arise together. Difficult and easy complement each other. Long and short contrast each other: High and low rest upon each other; Voice and sound harmonize each other; Front and back follow one another.
In order to have a great set/performance, there must be a overall journey with little ups and downs. The feel of the Killer Track is lost if all you are playing are Killer Tracks. There is a line people use – “All Killer No Filler”. This is a good idea, but it is incomplete. You must have and play tracks that are designed to chill the heat of the dance floor. Do not buy tracks that are not really “Filler”, but select tracks that are good while they can setup little valleys in the overall composition of the set.
