This is one of those books, that might be taken as essential for an understanding of the development of El Casino, the most favorite and important international cuban dance nowadays. As the music scientist Lino Arturo Neira Betancourt puts it: "The text deepens on the outstanding history of this dance and on the analysis, several evidence of its relation to contemporary Cuban popular music are revealed, as well as the protagonist role played by its best exponents through its development for the past five decades of the XXth century [...] It is certain that this book will change some current criteria about Cuban popular danzas inside and outside of our frontiers, but actually it demonstrates that the musical phenomenon called salsa has its competition in the international dance art, the casino."
