In Spain, the era of political transition to democracy known as La Transición during the 1970s and 1980s led to changes in Spanish popular music (i.e., pop, rock, punk) which became the musical representation of the new democracy’s social and political changes. Two different musical movements of that period, La Movida Madrileña and Rock Radical Vasco, established boundaries between official mainstream music and its musical counterculture counterpart, underground, and subversive musical practices within Spanish democracy. This thesis examines the nature of those musical practices, their song lyrics, and their social and political interpretations, including their influence on current musical practices.
