Sierra Maestra have a 30-year history of keeping the Cuban son tradition alive. They share founders with the original line-up of the Buena Vista Social Club, yet through the years Sierra Maestra have always mixed the classics of the Golden Age with newly written songs. Now, with five of the original members still in the group, they continue to find young talented writers in this son tradition and style. On Sonando Ya, Erden Hernández's lyrics are much more contemporary than usual, escaping the references and stereotypical images of the 40s and 50s. Arranger and composer Angel Bonne exhibits a brilliant new way of arranging the guaracha.
