Graduation or not, you still see people at festivals and other events do that same thing, just stand in front of the stage waving their hands in the air or crowd surfing as a CD or auto-synced loop is playing in the background. And that video is hilarious, even though that's what all these new "DJs" up and coming today would look like if you take away their effect every 60 seconds. Most of em are just flippin random knobs anyways for no reason the whole time, and if you ever go behind their computer screens they have a track playing with another one cued on a loop just so they can fade in or "scratch" into in a real shitty manner 5 minutes later. I don't have a problem with people doing that starting out because you gotta learn transitions somehow and someway, and thats a great way to start. But in the end, they don't move on to anything different and all sound the same. Literally, set to set sounds exactly the same.
I went to 2 Fools Gold and one Never Say Die event at SXSW last year and aside from Zomboy at the Never Say Die thing, everyone's set literally sounded the exact same throughout. Flosstradamus was just 140bpm-150bpm trap music for about an hour, and then changing the tempo briefly later on (I'm pretty sure that they played literally the same exact set 2 nights in a row, aside from one or two tracks), and all the other guys did that same either moombahton or trap for a full hour or so. Same goes with these other kids at parties playing the same exact mixture of the beatport top100, krewella, and skrillex type tracks just for hours on end. It honestly gets boring. I go to events for the variety of styles and a different approach to performance from person to person, so going to an event for 6 hours and seeing the same thing day in and day out gets frustrating. But where there is money and glam, the crowd will most certainly follow. What astonishes me is that people have all these auto-sync, auto-loop, and auto-cue options and can only use these tools to do just that. Auto-sync, auto-loop, and auto-cue for 90 minutes plus. A good performer would find a way to use those in a fashion to get those hassles out of the way, and replace the work that it takes to do those things with working to add a different form of uniqueness to the set. Instead, it's a lot easier to just be lazy, do less work, and jump up and down while waving their hands in the air. And worst of all there are groups of duo-DJs today who do this for 90 minutes!! How can some of the really good guys do 10 times more on their own in a set than groups of duo-DJs? Is it that one stands there and acts like their doing something while the other does the minimal work? Or is it that complex to learn how to auto-loop and auto-sync that it takes more than one person to do it (How many new "DJs" does it take to screw in a lightbulb?)... I respect a guy who continuously fucks up while trying to put on a mind-blowing performance wayyy more than a guy who plays a set with minimal mistakes that is just bland and boring. The aspect of fucking up shows that they are pushing their comfort zone, and will only improve from there.
Playing tracks that can make people move is easy. They are already made for you and all you have to do is press play, and people will move to it for 3 minutes. Playing a moving set for more than 3 minutes at a time takes not necessarily endless talent, but definitely a lot more effort. Guys like Jimi Hendrix and Eric Clapton would practice their guitars 8 hours plus a day. One of my friends recorded a track with his band in Eric Johnson's studio, and the mastering engineer or tech guy that worked there said Eric practices his guitar 8-10 hours plus a day in a small little room without even taking breaks. Few DJs do that today. Most of these kids just listen to party tunes then go play a party once every while and play the same thing they did the time before. How many hours of working on sets to they do a week? I'd say no more than 1 or 2. Maybe they play multiple sets but it usually isn't to expand on their abilities or general wisdom of performance. It's just because they are bored and feel like doing it.
Music today is more about the image, and less about the talent, at least in the US. Hence why you have ignorant, talentless fucks like Miley Cyrus and Justin Bieber being worshiped while nobody really knows who the fuck someone like Mimi Page is (just an example). Go to the UK or other areas of the underground scene in EU, you will run into guys who put more heart and soul into their sets. Not that there aren't guys here in the US that do that, but they are much fewer and farther between.
