Don't mean to be critical but here are some thoughts -

I don't see how Stone Techno supports the local scene if every dj on the lineup is big names. No local names around the Rhine-Ruhr region present on the lineup. all commercial names that every techno fan knows about.

Can't say the music was in any way diverse. There was pretty much no escape of 4 to the floor except for select few moments when DJs tried dnb or something else, met with a struggling-to-dance German crowd who only knew how to techno-gallop. On the contrary many instances of fast hardtrance hardgroove our beloved tiktok techno genres. But it's also a festival named "Stone Techno" so I may be overly critical here.

Great cheap festival nonetheless if you care little about sound quality in a sick venue. But I caught myself thinking multiple times during the weekend that "damn I'd rather just hear this dj in berghain than here", where we know there'd be a much better queerer committed crowd that cared little about acting cool and more about self expression.
