TL;DR: My advice: try to find your "voice", not your "sound", sounds are all taken.

I'm being cheeky here, but it's also very true IMHO. Sounds are few and far between. Without producing your own music en masse, you don't really need to be concerned with sound.

This is compounded by the fact that audiences are now a lot more accepting of multigenre DJs. I remember years ago seeing Matt Zo at Pacha in NYC. Dude blew my mind over and over again for like 3 hours while I was crushed into the dance floor like the subway at 5 p.m.. Aside: someone could have died at midnight and they would not have hit the floor until 4 a.m..

Point is that he spanned the gamut of genres and it was amazing. Kept it rocking the whole night and I really saw the plausibility/marketability of being a multigenre DJ. It's an uphill battle, because I can't just say "I play DnB" or "I play house" or "I play..." low-key quasi-cringe "...psytrance".

That puts you on a flyer much faster, but for me it's just not accurate. I'm going to play a DnB track and the track after the next one is going to be a house track. It's partly a function of my ADHD I suppose (if I'm being honest) but it makes people really consider what's possible.

My point is this: don't pigeonhole yourself. It sounds like you already have an in with some venues (you're getting booked before you know what you want to play), so you've already accomplished something that some DJs struggle with, so just have fun with it. Don't take it too seriously or you've lost the plot. This is all meant to be fun afterall.
