Rock music and its subgenres are very popular in Portugal. The history of the Portuguese rock music scene spans several decades. History 1950s to 1970s In the late 1950s, singer Joaquim Costa was one of the first rock artists, but it was only during the 1960s that the genre's popularity began rising, with bands such as "Quinteto Académico" and "Sheiks", who played mostly in clubs and student associations. Most of these groups played covers of American and British bands or were influenced by artists such as the Beatles and The Shadows.

During the 1980s, Veloso's blues-rock sound achieved national success and inspired the creation of several rock and roll bands, which became popular with youths growing up in the post-1974 modernized Portugal. The success of groups like Taxi, Heróis do Mar and Trabalhadores do Comércio, indicated that a solid rock scene was growing, despite the fact that these were all relatively ephemeral projects. Xutos & Pontapés are arguably the biggest success case in the Portuguese rock scene, having become the first band in the country to celebrate 30 years of career.
