just like like the girl from twitter that Op posted, there are plenty of examples of black brits on this very board that are in denial.
Well, first up with the twitter poster, thats one person out of 2mil who got arrogant on social media. Some on here do this too, so this may be the case online, but not in real life.
And I specifically said '100% black british made', meaning we have our own culture and local character, but most will admit that a bulk of it comes from other cultures. If you came here and spoke to the black population about it, they will deny some things, but you wont really find anyone here who thinks every last thing we do was started solely by us.
Its when claims that sound

aframs were known/mainstream in the UK, such as the people you mentioned but the stuff that black british youth's were seeking out from black america (what they call rare grove) wasn't mainstream even in the USA in the late 1970's early 1980's
how can we deny that this happened when we can see how black british music unfolded from the early 80's to present? Black Brits went from hiphop and obscure funk (rare groove) in the early 80's to Chicago House and NYC garage by the mid 80's. By the time the 90's came, Black Brits were always doing some spinoff/remixing of any and everything that came out of black america musically during the same time span and it continues as we speak. Today you have UK Drill acts and it's not like Drill music is all over TV/Radio. Drill music isn't even popular in the USA so I doubt it's mainstream in the UK but it's because they seeked it out.
I never said black british musicians didnt continue to copy/be influenced by black american music, just that most (but I accept not all) of the black american music copied after rare groove was mainstream over here rather than obscure. Plus, even if black brits seeked out an obscure part of black american culture, black american culture itself WASNT obscure in england so its not as if people were searching through something that was entirely unknown. You'd have a point if it were an obscure part of lets say, 'mexican' culture which never has had any prominence in the UK whatsoever. That was more or less my original point.
There are other factors which also helped black american culture spread to the the UK over the years that I think should be bought up. In recent years, the internet. You dont really have to search hard to find anything that blows up anywhere with a big enough population, seeing how advanced 'media connections' are these days. You brought up drill music, which is a subgenre of Hip hop which has needless to say, always been huge in the UK since it began. So anyone around the world paying attention to the american hip hop scene would've definitely got wind of drill if thats what is making a buzz over there. And hip hop fans worldwide will ALWAYS pay attention to the american hip hop scene, because why wouldnt they pay attention to the nation that birthed the art form. Same way manga fans will always focus on japan and kung fu fans will always focus on china. Youtube and social media are the main reasons why something like drill can never be obscure.
The next factor which I believe helped black american music spread to the UK outside of whats mainstream is the caribbean diaspora. Almost every caribbean person I know has family in the US and its likely thats the main reason why black people over here fly out there. Even i got family over there on my caribbean side, but Ive never met them. The US, UK & canada always top a caribbean citizen's destination list outisde of other caribbean nations. The local music in any caribbean hotspot in the US (New York, florida...) may have spread to Britain this way. This is just a theory that is worth considering, im not asserting obscure music definitely spread here due to this.
black brits tryna flex and take shots at a big part of their foundation is the only reason![]()
I'd say 'evolution' is more accurate than 'foundation'
