Living in Germany, I can confirm that it’s part of the everyday scenery here (Stadtbild).

> and a rave

I can confirm that techno culture is a deeply rooted part of the urban landscape. However, the era of massive, free street parades effectively ended with the 2010 Love Parade tragedy in Duisburg, where a crowd crush claimed many lives. For years, such large-scale public raves vanished due to strict safety regulations. It’s only recently that we’ve seen a revival with 'Rave The Planet' in Berlin—an event led by the original Love Parade founders that attempts to bring techno back to the streets, though under much tighter organizational control.
