As a DJ one of the best indicators are robust social media presence. The more personal the better. If there's nothing but a sterile business only acct beware. It's not a 100% thing. Plenty of us aren't fond of the socials. But typically speaking this genera is more passion than business, and it will find a way to show.

I was a bit wary of a band called Midnight Darkwave, found them on YouTube. There was a similarly named YouTube channel that was clearly using some gen AI. At least for visuals looping under the music. No band camp presence. And the mastering of the tracks triggered a feeling of AI. I dug a bit and found their insta. With clips of them playing etc. Mostly in studio, but convincing enough. That's the best and only real way.
