Answer:
During the 1940s and 50s, Cuban musicians had a huge influence on the New York music scene.But once Fidel came to power, diplomatic relations fell apart between Cuba and the US. Cuban musicians could no longer travel to the United States and Cuban recordings received no air play time. So the Puerto Rican and NuYorican (New Yorkers of Puerto Rican descent) musicians took on The Big Apple single handed.
These days New York salsa has a distinctly Puerto Rican sound ‚ smooth, polished, classic salsa. It tends to follow the jazz structure, incorporating lengthy instrumental breaks to showcase the ability of particular musicians.
Leading musicians playing NewYorican Salsa:
Celia Cruz
Willie Colon
Eddie Palmeiri
The Spanish Harlem Orchestra
Jimmy Bosch
Hecor Lavoe
A good Salsa song is El cantante - by Hector Lavoe
another is La Vida Es Un Carnaval - by Celia Curz
If you need more info, let me know. Im Puetro Rican, so thats how i know alot on this.
Hope I helped :)
