Los Iracundos are a rock and roll band that rose to prominence in Latin America during the 1960s, at the peak of the Nueva ola music movement. The band formed in 1958 at the city of Paysandú in western Uruguay. Soon after its founding, the band participated in the Uruguayan Invasion, a music craze which swept Argentina in the 1960s. From there, the band rapidly expanded in popularity in countries such as Chile, Peru, and Mexico.
After the death of lead singer Eduardo Franco in the late 1980s, the band has continued to perform with different members.
