We’ve all been there, walking into the club only to be confronted with an opening DJ pounding out the biggest peaktime tunes to a sparse crowd of early arrivals who are more concerned with checking their coat and grabbing a drink than sweating it out on the dance floor. It’s the first no-no of the warm-up DJ set, and is repeated by all of the star jocks—including Josh Wink, Hector Romero, Mike Huckaby and DJ Dan—in a recent blog post by NYC DJ school Dubspot. Other tips include making room for the next DJ in the booth, not dropping the headliners biggest hit right before he goes on (duh) and packing something “throwback or silly” which according to DJ Shiftee will make your set memorable without messing with the vibe of the whole evening.
