Funk was the culmination of all Black American music made up until that point (Gospel, Blues, Jazz, R&B, Soul), and was created by some of the absolute best musicians from those genres that wanted more freedom in their musical expression.
It was the music of the 70's in Black America, and was the main influence on Hip Hop's sound from the late 70s to the early 00s.
The drums that fueled most of the classic hip hop records from that time were lifted mostly from Funk records, the bass lines that drove these records were mostly Funk inspired, and the melodies/rhythms from Funk or Funk inspired records provided an infinite source of samples, ideas, and inspiration.
Artist's born in the 60's/ 70's/early 80's were raised in households and environments were funk music and funk inspired R&B, Soul, and Jazz was THE music of the black community.
We were raised on shyt like this...
My theory is kids born from the late 90s on, were more influenced by the internet than their families/communities musically, and the music being made today is a reflection of that.
A lot of us older cats were late to the internet movement, and by the time we got our footing, youngins was already on some way other shyt, so the shyt we was talking about was foreign to them.
Correct me if you feel I'm wrong..
