While there's nothing wrong with looking forward and looking for the means to improve things, doing so without paying attention to one's history can result in the creation of a cultural vacuum. Far too often in North America we're far more concerned with celebrating the next "Big Thing" and then discarding it once something else catches our eye. Instead of using what came before as a foundation for building something solid, far too often we end up with confections which, while looking good, are the artistic equivalent of candy floss. Lacking any real substance they usually blow away the first moment our attention is distracted by the next shiny pretty thing to come along.
Initially, popular music in North America was close to its roots, building on the solid foundation of both its African American and European roots. Even before rock and roll and the successful marriage of country and blues, composers like Ira and George Gershwin drew upon jazz and blues influences when composing some of their most famous pieces. Porgy And Bess should have been a defining moment in the development of a uniquely American culture in the way it combined the classical form of opera with the music of the new world. Unfortunately, commercial necessity forced the brothers to divert their creative energies into musical theatre and eventually film. While songs like "Summertime" might live on through their occasional revival, Porgy and Bess isn't usually seen performed outside of opera houses, and the Gershwins are remembered more instead for the insipid music they wrote for Hollywood musicals.
Popular music in North America has been like a series of coups and counter-coups as in almost every new generation a type of rebellion occurs against what came before; rock and roll in the 1950s, psychedelic/acid rock of the 1960s, punk in the 1970s, rap in the 1980s and grunge in the 1990s, only to see each one co-opted and watered down by an industry geared towards treating development as a trend to be milked for every dollar possible. Having lived with this reality most of my adult life, it always comes as a nice surprise to discover parts of the world where things are different. Not only do musicians and audiences recognize the importance of their cultural history, they see nothing wrong in playing and listening to the music their fathers and their fathers before them played. One doesn't even need to look too far from our own shores for an example either, for Cuba's Septeto Nacional has existed since 1927 and is onto its fourth generation of players. One of the original son bands who first combined the African and Latino sounds of Cuba, the latest incarnation's new recording, Sin Rumba no hay Son! (Without Rumba there is no Son), is being released September 14/10 on the World Village Music label.
