Rock and roll first broke into Uruguayan audiences with the arrival of the Beatles and other British bands in the early 1960s. A wave of bands appeared in Montevideo, including Los Shakers, Los Mockers, Los Iracundos, Los Moonlights, and Los Malditos, who became major figures in the so-called Uruguayan Invasion of Argentina. Popular bands of the Uruguayan Invasion sang in English.
