If anything, NYC is culturally Black. Almost everything NYC is known for comes from Black ppl since the creation of hip-hop. The lingo, the clothes....most modern impersonations of someone "from NYC" is usually of a Black person.
My favourite firework video on the internet is this one, where 45 minutes worth of fireworks are accidentally detonated all at once on July 4th 2012 in San Diego. I had tears in my eyes, sobbing the first time I saw this. The sound is magnificent. It's the end of days.
