Argentine rock, called "rock nacional", is the most popular music among the youth. Arguably the most listened-to form of Spanish-language rock, its influence and international success are owed to a rich, uninterrupted development. Bands such as Soda Stereo or Sumo, and composers like Charly García, Luis Alberto Spinetta, Fito Páez and Andrés Calamaro are referents of national culture. Mid-1960s Buenos Aires and Rosario were cradles of the music, and by 1970, Argentine rock was well established among middle class youth (see: Almendra, Sui Generis, Pappo, Crucis, Pescado Rabioso). Serú Girán bridged the gap into the 1980s, when Argentine bands became popular across Latin America and elsewhere (Enanitos Verdes, Fabulosos Cadillacs and Virus). There are many subgenres: underground, pop-oriented, and some associated with the working class (La Renga, Divididos, Hermética, V8 and Los Redonditos). Current popular bands include Babasónicos, Los Auténticos Decadentes, Rata Blanca, Horcas, Attaque 77, Bersuit, Los Piojos, Catupecu Machu, Carajo and Callejeros.
