<human>: Buena Vista Social Club is an ensemble of Cuban musicians established in 1996 to revive the music of pre-revolutionary Cuba. The project was organized by World Circuit executive Nick Gold, produced by American guitarist Ry Cooder and directed by Juan de Marcos Gonzalez. They named the group after the homonymous members' club in the Buenavista quarter of Havana, a popular music venue in the 1940s. To showcase the popular styles of the time, such as son, bolero and danzon, they recruited a dozen veteran musicians, many of whom had been retired for years.

The first performances by the full line up of Buena Vista Social Club, including Cooder, were those filmed by Wenders in Amsterdam and New York. Other international shows and T.V. appearances soon followed with varying line ups. Ibrahim Ferrer and Ruben Gonzalez performed together in Los Angeles in 1998 to an audience that included Alanis Morissette, Sean Combs, and Jennifer Lopez, Ferrer dedicating the song Mami Me Gusto to the Hispanic Lopez.  Performances in Florida, which has a large Cuban exile and Cuban American community, were rare after the release of the film due to the political climate. In the late 1990s, a concert by Cuban jazz pianist Gonzalo Rubalcaba turned into a near riot when concert goers were attacked and spat at by protesters opposed to the Cuban government. When "Buena Vista" musicians played for a music industry conference at Miami Beach in 1998, hundreds of protesters chanted outside and the convention center hall was cleared briefly because of a bomb threat. In 1999, Ferrer and Ruben Gonzalez were forced to cancel Miami shows citing fears for their safety after fellow-Cubans Los Van Van drew 4,000 protesters at a previous show, and Compay Segundo was forced to cut short a 1999 Miami performance due to another bomb threat. When touring the U.S., the Cubans are only entitled to their per diem (transportation and lodging) and are not permitted performance fees due to the U.S. embargo. In 2001 a Buena Vista Social Club (with Ibrahim Ferrer) performance was recorded in Austin for PBS and broadcast on Austin City Limits in 2002.  Buena Vista Social Club continue to tour throughout the world as Orquesta Buena Vista Social Club, and despite the deaths of six of the original members, the collective performs with many of the remaining ensemble members including Barbarito Torres and "Guajiro" Mirabal. Ry Cooder's guitar parts are handled by Manuel Galban, a former member of Cuban vocal group Los Zafiros, who played on Ibrahim Ferrer's first solo record with Cooder and appeared in Wim Wenders' film. Following a 2007 performance in London, a reviewer at The Independent described the ensemble as "something of an anomaly in music business terms, due to their changing line-up and the fact that they've never really had one defining front person", adding, "It's hard to know what to expect from what is more of a brand than a band."
