i think he means big jumps in key in essence it depends entirely who your audience is. 9/10 when you are playing the 'bangers' most of the punters in the room could give a shit about key. while mixing in key generally helps produce a nice fluid mix its not always essential. while you still might not be mixing in key, a mix can still be exceptional. good skills can-to a degree-make up for poor track selection. at the end of the day there have been enough 'bangers' produced to establish a relative key gradient amongst popular tracks in edm. i use the term 'bangers' in quotes due to the subjective nature of the term. to an educated crowd, a great track produced by someone not many people have heard of can be pretty much the greatest, best, most fantastic (which ever way you wish to describe it) track in the world. because it is appealing to the culture and values of the crowd. This is obvious when you (for example) make your way into one of the many cruisey bars and bistros where 1 dj in the corner is running some deep house tunes that no one has ever heard of and yet set an unbelievable vibe. while the tracks do not meet the necessary convention of 'popular' this doesnt stop the dj from doing his job. that is the end of my point of 'bangers' back to key. the reason nobody cares about the big key jumps that often occur when one poorly prepared dj jumps from one 'banger' to the next is that for that crowd simply knowing the song is enough. You simply don't here the big club 'bangers' being played in areas without alcohol because that is part of the environment, the scene, the right setup for those tracks, to be screamed and shouted by a bunch of pis-pot teens still halfway through their 3rd cruiser at 2am. and to be honest, even for the learnered few when you've had a few to drink you dont really care that much because THAT guy who feels more obliged to sit there and point out poor music choices, or sloppy mixing skills is missing the point of being in that environment in which he openly critiques-to have a good time. If sitting there all night and doing that is your idea of a good time, each to their own but you would fall in the minority. i guarentee it. at the end of the day, as a dj, you are there to please the crowd. THIS IS YOUR JOB. while you also want to have a good time, generally you are paid to be behind the decks (or if your not, then your representing yourself and misrepresent yourself with poor skills is to your downfall) so you are on somebody elses time. do your job or you will quickly find yourself out of one in this business. Most of the time, your job is a to please the crowd of punters who just want to relax and have some fun, provide that and then worry about if your mix of 'bangers' where in key later. if your attending a dj comp where they are actively judging your skills then feel free to flex your selective muscle and internet/cd/record store searching prowess. Remember your crowd, who you are trying to please, what you want the mix to achieve and you wont go too wrong. mixing in key helps, but picking the right song for the room comes first everytime /walloftext alexj out Totally agree with this, exactly what i thought!! Thanks everyone for replying, really helpful stuff!!!
