Also, by "rap" I think you mean 'hip-hop', which includes sampling and mixing, especially using turntables.
> Well, blues is the son of jazz music :)
Try some Muddy Waters and John Coltrane, listen, then report back.
With due respect, beyond every form of music being related to every other (just like you are probably a distant relative of mine), they are such different genres that my impression of the comment - which could be completely wrong - is that the commenter has not listed to jazz, blues, or both.
And I’d argue that blues and rock are separate, but that most rock until late 90s was heavily influenced by blues. But that’s all just fun trying to draw lines where there isn’t a clear difference sometimes.
PD: I didn´t put Blues/Rock as separate entities, but two genres where late blues albums could be considered something as proto-rock. And ditto with jazz-swing-blues. It's like a continuum.
Black people in the US invented basically the three modern music roots:
- Blues/Rock
- Techno
- Rap
The problem is rap had much better marketing in the US, ditto with rhythm and blues in the 90's.
