How can Hip Hop create something new when the basis of it is the music of the 70s and 80s?
Hip Hop is a technological and sociological innovation, not a musical innovation. The makers of Hip Hop can't read music. Aren't proficient at playing instruments. Can't sing on key. Even the production techniques are rather simple and rudimentary compared to Techno and other forms of electronic music.
The strength of Hip Hop music is the fact that it's rooted in Funk and Jazz, it's the beat and groove and the swing. It's the soul, it's the 70s Black American music. It's the Blues.
It's not an insult, it's the truth.
Hip Hop is a case study of how technology democratized music making and how digital technology will lead to copying and reinforcing what already was created.
Which is why Hip Hop is the last frontier of popular music. There will be nothing else after it because each generation after Hip Hop, as the original Hip Hop generation has done, which is copy the music of their parents and older relatives. Gen Z and Alpha, literally copying Y2K popular culture. Millennials will most likely be the last generation that attempted to create something novel but ended up copying. Every other generation will openly and brazenly copying because that's how our technology easily allows it which has influenced our cultural production.
As Hip Hop and it's method of music creation has became dominated popular music, we went deeper and deeper into nostalgia and remaking what is already here.
Hip Hop is recursive, self-referential youth culture and music. You can't point to single new thing within the genre of Hip Hop that didn't already exist because that's how the genre itself was conceived.
Something new in hip hop that didn't exist before it...the ways and methods in which samples are used to craft new records. The structure of how rap songs themselves are written. Both of those things have gone on to influence music since hip hop's inception. And thats just 2 things. Now you can keep insulting Black people under the guise of defending Black Americans with backhanded compliments. I'll keep just giving the credit flat out without having to denigrate any group of Black people to do it.
