Shortly after the Cuban Revolution of 1959, newly elected Cuban President Manuel Urrutia Lleo, 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 Rodriguez and Pablo Milanes. 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. Cuban music experienced quite a radical change in the 1960s, as National Geographic notes: Cuban dance music also witnessed dramatic change beginning in the late 1960s, as groups explored the fusion of Cuban son with American rock, jazz and funk styles. Groups such as Los Van Van and Irakere established modern forms of Cuban music, paving the way for new rhythms and dances to emerge as well as fresh concepts in instrumentation. ... Cuba's dance music had already inspired a change from the older son-style dances, as younger Cubans broke free of step-oriented dances... The occurrence of these closures and the change in traditions is the simplest explanation of why many musicians were out of work, and why their style of music had declined before the Buena Vista Social Club made it popular again.
