Okay fine, this one’s for the nerds. Selena: The Series has me thinking a lot about Latin music. I mean, I’m always thinking, listening, feeling Latin American music. I’m also thinking about what that means. When there are so many countries across continents, with different histories and unique dialects and sounds, how can it all just be under one banner? Pablo Palomino takes a look at the history of the genre, zooming in on the 1920s to the 1960s, and tries to understand its success. Everyone loves a Latin party.
