No.
I had a DJ Soundcloud page, but once I got well-known enough for my name to get people through the door, I stopped doing demos and mixes ... (I hate it ... much prefer to play live) ... so, that went the way of the dodo years ago now.
I tried my hand at production for years but wasn't terribly good at producing from scratch though, so gave it up and focused on the DJing, with the occasional foray into remixing — I did a couple of colabs in the Past and produced a handful of remixes (five)... but nothing you'd call hugely commercially successful (popular enough on the underground scene, but nowhere near mainstream success).
Covid killed the party scene ... and I'm not sure how confident I'd feel about going back to spending days on end in hot rooms full of people just back from who knows where until it's finally all over anyway ... so I've pivoted to production
But it's early days yet and I haven't produced anything good enough to even put up for people to listen to and give me feedback for, let alone release. Obviously, I'm not a complete novice but ... even with a lot of experience as a DJ and a lot of knowledge about production gained over the years, I'm having to forcemarch myself through a very steep learning curve. Fair enough, I'm up and running pretty quickly but I'm having to spend a lot of time finding my way around things — I've never actually done synthesis before, just used presets and stems/loops/samples, so there's a lot to learn before anything I produce will be good enough to release.
Watch this space though — I'll be releasing some nailcore filth as fast as I can 😉
