RANDOMNESS: Top Five Codes of Conduct For Opening DJs at EDM Shows

1. Do NOT Play the Top Songs on Beatport 
Anybody can play bangers all night, it’s another thing to be creative with your time slot and still get the crowd pumped up. The big guys have earned the right to play the headlining spot and thus reserve the right to play the songs of the season. Don’t make them edit their set and go to different cuts because you don’t know your role in the show. Have some respect and common sense and use it as an opportunity to be creative with your artistry.
NOTES from The Librarian: Play vinyl, keep it slow and keep it older (5 to 10 years back), you can play a few "old school" classics but don't hog all the classic by stringing them together.

2. Do NOT Play the Artist/DJ’s Songs 
It’s an honor to open for the artist and play in front of their fans, you should support the show accordingly. The hundreds or thousands of people in the crowd are most likely there to see the headliner play their songs. Don’t be the idiot who tries to steal their thunder. Show some respect to the those who have actually produced their own tracks, been picked up by a record label and put their music out on Beatport.

3. Do NOT Play Songs Like “Put Your Hands Up”
Between 10pm-12pm, guests are arriving in the club, buying their first drinks and getting settled. They aren’t ready to throw their damn hands up until they’ve had plenty of drinks in them and they see enough people getting wild. Also, they aren’t ready to “Save the World” before midnight. Any DJ who blows their load too soon will leave the crowd wanting for the rest of the night.

4. Do NOT DJ Into the Red 
There’s a real tendency for opening DJs to think they are the star of the show. When you play fast, hard-hitting songs above 128 bpm into the red or put the volume at level 10 the system gets maxed out and the room is way louder than it should be that early in the night. It’s easy to get carried away with the energy and excitement, but you give the headliner no room to adjust the volumes properly and effect their sound.
NOTES from The Librarian:  If you ever put a mixer into the red I hope a sound engineer or an older DJ comes by and smacks you off the decks. Personal pet peeve.

5. Do NOT Unplug Anything 
After you leave the decks it’s obviously crucial to leave the RCA cable and any ground wire in place with no excuses! If you are going to do this then you probably shouldn’t be an opening DJ and need to find a new career path. Being an opening DJ requires a unique skillset and venues need to be screening them to make sure they recognize their position and follow these simple DJ codes.
NOTES from The Librarian:  I hear this logic but I will admit I will generally have to unplug CDJ's to connect my dub siren and my sampler in. However I generally unplug and replug things in during my own set so as to not cut into other peoples time slots.
