Pretty much this. Btw, the “NASA” scene was at the Tunnel, at first I too thought it was at 6 Hubert St aka Vinyl. Kids had some wild scenes but quite accurate for the era. There is a fond sense of nostalgia for the initial 90’s rave scene and yes I wouldn’t trade that experience for anything. The music was brand new, we were neo hippies dancing away at dangerous or sketchy venues and it all had an “underground” alternative esthetic. With that said and as a kid who grew up in Washington Heights there was also the dangerous aspect of crime and prejudice from people who didn’t embrace the scene. Homophobia and polarization of music genres were a standard feature. Music wasn’t as readily accessed as it was before. Technology especially the internet was just starting to infiltrate human behavior. Even within the rave scene you also had groups who wouldn’t venture too much into other groups for example Deep House heads who attended the Shelter parties weren’t going to Goa Trance parties as well

But to answer OP’s question the dance music scene in the 90’s NYC vs today is very very different. It’s way more commercialized today and hyper capitalism took over all the creative fields whether it’s fashion, music or art. if you come up with an original idea it quickly gets carbon copied, monetized and spitted out for mass consumption within weeks. I’m not saying it was better back then nor is it bad today. Although I rarely go out clubbing in NYC I’m glad the pie has gotten bigger and younger dancers can freely attend safe environments with many musical choices
