zackster no way are they “Perc school” - for sure Perc’s current productions are incredibly “crisp and clean”, and occasionally he might use a gabber-esque kick-drum, but that’s where the similarities end. His breakout tracks weren’t even crisp either. His sound is incredibly drum/percussion focused. He rarely has any melodies at all. He also leans more towards the 80s/EBM side of things anything resembling 90s hardstyle/gabber/euro stuff. Ultimately, it’s very British somehow, not “Euro”.
I also don’t think Dax J “falls in between” Hadone and Perc - he has a lot in common with the Perc industrial side of things, but he’s very far from the Hadone euro style, I’m not sure he’s come close to touching it at all. I’ve generally considered Dax J more falling between the Perc industrial/British style and the more loopy old-school Detroit, Ben Sims etc. style.
Yes Nina is very all over the place, but she was frequently playing 90s fast trance and psy-trance stuff in contemporary techno sets pretty much before anyone, which partly opened the doors to the euro/scandi stuff. She also now plays all the big promos of that euro/scandi stuff alongside all the other random stuff she still does.
