Hi! I´m spanish so I can tell you somethig about flamenco
.
I think that people outside Spain see flamenco as the steriotipe spanish music but it is the traditional music of just one region of spain: Andalucia. However it has influenced a lot of music outside Andalucia. Im not from Andalucia so I have never been in touch with flamenco so I can´t tell you as many thing about it as I would like to, but I can tell you that Paco de Lucia was one on the greatest Spanish player,that dude was a shreder! The few thing that I have listened of him are awesome. I have never listen to Rosalia but I know that she "mixed" flamenco and trap.
If you want to listen to other flamenco artist Camaron is a good point to start
