Estopa are a popular Spanish rock/rumba duo from Cornellà, Spain. The band consists of the brothers José and David Muñoz, who sing a unique blend of sounds reflecting many genres, including rock, rumba, flamenco, and a "sonido callejero" that does not easily fit into categories. The band has commented on such difficulty by stating "We don't like to be easily categorized." They are similar to the band Los Chichos, a rumba band from Spain, popular in the 1970s.
