Shortly after the Cuban Revolution of 1959, newly elected Cuban President Manuel Urrutia Lleó, a devout Christian, began a program of closing gambling outlets, nightclubs, and other establishments associated with Havana's hedonistic lifestyle. This had an immediate impact on the livelihoods of local entertainers. As the Cuban government rapidly shifted towards the left in an effort to build a "classless and colourblind society", it struggled to define policy toward forms of cultural expression in the black community; expressions which had implicitly emphasized cultural differences. Consequently, the cultural and social centers were abolished, including the Afro-Cuban mutual aid "Sociedades de Color" in 1962, to make way for racially integrated societies. Private festivities were limited to weekend parties and organizers' funds were confiscated. The measures meant the closure of the Buena Vista Social Club. Although the Cuban government continued to support traditional music after the revolution, certain favor was given to the politically charged nueva trova, and poetic singer-songwriters such as Silvio Rodríguez and Pablo Milanés. The emergence of pop music and salsa, a style derived from Cuban music but developed in the United States, meant that son music became even less common.
