Héroes del Silencio (well known as Héroes or HDS) was a Spanish rock band from Zaragoza, Aragón, Spain, formed by Juan Valdivia and Enrique Bunbury. During the 1990s they experienced success around Spain and the Americas, and in various European countries including Germany, Belgium, Switzerland, France, Serbia and Portugal. They established themselves as major contributor to the Rock en Español scene. After ten years and numerous albums, the band broke up in 1997. When the lead singer Enrique Bunbury started a solo project, other members of the band also followed a different musical path. In 2007, as part of a 20-year anniversary celebration and 10 years after their break-up, they organized a 10-concert world tour.
