Book excerpt: Rondón tells the engaging story of salsa's roots in Puerto Rico, Cuba, Colombia, the Dominican Republic, and Venezuela, and of its emergence and development in the 1960s as a distinct musical movement in New York. Rondón presents salsa as a truly pan-Caribbean phenomenon, emerging in the migrations and interactions, the celebrations and conflicts that marked the region. Although salsa is rooted in urban culture, Rondón explains, it is also a commercial product produced and shaped by professional musicians, record producers, and the music industry. --from publisher description.
