any type of djing is about making the right sound at the right time.

what sound that is will depend on the context of the other sounds you've already played. i think that "tricks" sound much better when properly setup. ie, set the stage, or foreshadow what you are going to do, build anticipation, then deliver the goods, give them a bit of time to appreciate what you just did, then move on to the next idea.

but trick after trick gets boring and takes away from the music.
