Hoi, guys, not so fast here.
Sure, there's lotsa show today where digital decks enable practically anyone who cares to do some sorta mix but there's more to it than that, way more. Different tracks have different sounds/atmos, one sounds brighter, the other sounds darker, one has more bass, the other track is very bright but not so bassy, etc., so in order to shape the sound and create something new in the process, you gotta EQ quite a bit to prevent harsh cuts. Sometimes that's just what's needed, on other times you need something more smooth, for ex. if you're doing a low-bpm thing with some ambient mixed in.
You also gotta keep the volume/loudness in check. If you do varied sets with old and new music (say roughly from the 60s to now), you can't just throw in a Stax track from 1965 next to a current hip hop production (which more often than not means a victim of the loudness war) without adjusting things a bit, or a lot.
Then there's the cueing, which means setting things so that two records/tracks play in sync. This used to be one of the core elements of mixing until auto beat matching appeared, you gotta adjust things a bit here and there, depending on the track, some are very difficult to mix coz they aren't beat exact or have tempo changes so again, you gotta fiddle around quite a bit to get that down.
And then there's stagefright, tension, inner drive... yeah, well, maybe misses Hilton is missing out here a little, parts of the thing have become a bit of a farce in this day and age where ppl with their Denons and AlphaTetas and Pioneers can be multi-million-$ superstar DJs. That's okay, tho, the upper class here is one of its own that has not a lot to do with what's going on music-wise so they don't count in the grand picture.
Sometimes I wanna molotov their friggin' decks. One day I will, watch this space - - -
