During the 1960s many prominent groups emerged such as: Grupa 220, Crveni koralji and Roboti. The latter featured Ivica Percl, who after leaving Roboti in September 1966 because "they were too loud", became a protest singer-songwriter influenced by the acoustic sound of Bob Dylan, Donovan and Joan Baez. In the same year, the internationally acclaimed Croatian chanson-influenced singer Tereza Kesovija represented Monaco in the Eurovision Song Contest 1966. Another notable female vocalist who emerged in this period was Josipa Lisac (later Karlo Metikoš's wife) who still enjoys huge popularity in Croatia.
