This information was sent by Patrick about a documentary called "Mambo to Hip-Hop" by Henry Chalfant. Here is the excerpt:
Mambo to Hip Hop: A South Bronx Story features Luis Chaluisan as the narrator: Eddie Palmieri, Ray Barretto, Benny Bonilla, Orlando Marin, Manny Oquendo, Willie Colon, El Extreme, Africa Bambaata, Kool Herc, Charlie Chase, Fabel, Kid Freeze, Track II, Trace, Bom 5, Sandra Maria Esteves,and more. The film presents a panoramic view of the music that blossomed in the latin community of the South Bronx from the late 1940â€™s when mambo burst onto the New York cultural scene through the birth of hip hop in the 1970s. The film chronicles two generations who grew up literally on the same streets, and both used rhythm as their forms of rebellion – for the older generation it was the pulsating rhythms of Cuba; for their children it was the rhythms of rap. The film, designed for public television and possibly theatrical release, aims to bring attention to the Bronx neighborhoods and communities who, with few resources, transformed the worldâ€™s pop culture. Mambo to Hip Hop: A South Bronx Story, release January 2006, an hour long documentary produced by City Lore, Inc. and directed by Henry Chalfant.
I think this can be a very entertaining and powerful documentary in connecting different dance styles – and the whole Latin-New York culture during that era.
