This is that NewYorican music that came up in the Sixties and Seventies in the great city of New York. Salsa; Latin Jazz; La Musica; call it what you will. It was great music, and it was the most happening scene in New York at the time.
Happening, you say? Oh, yeah. Prettiest girls; best dancing; best parties; best drugs; best musicians; most energy; most enthusiasm. Super sophisticated, ultra-cosmopolitan. If you had friends in this scene, and you could hang out, then you were happening, too.
(Disclaimer: I had friends in the scene in the Seventies, and I hung out a bit, but I never clubbed or went too deep. Still some of my fondest memories of the times, though.)
