OK, so I can pretty much name a "professional" disco setup these day (and this is for the guys charging a decent fee)
Starlit booth
Vertical Truss either side of the booth with moving heads/starballs
+ uplighting behind the DJ
Some might include a Martin rush on sticks either side of the booth
So that's the current "look" for a mobile DJ (plus/minus some extras).
What's the signs of the next trend? What can be done to stand out (in the right way)
Thinking mainly wedding look here.
