It's right by where the Capitol Hill block party is run, legally and with the city's blessing, every year. That's a major corporate event with _significantly_ more powerful sound systems.
I was referring to the "block party" feeling of European "autonomous zones", i.e. in variaous European cities like Hamburg, Berlin, Kopenhagen, Barcelona, …, where Antifa/Anarchists/Far-Left "took over" an area/building, with city-officials telling the police to back-off, which created "never ending block-parties".
Growing up there, seeing that it was always the same no matter which city or country, was the best vaccine against their school of thought.
