The band Crni Biseri (The Black Pearls) was formed in 1963. They took the name from famous yugoslav 50s movie about young delinquents. In 60's they played beat/60s punk/rhythm'n'blues. They were winners of the song festival Gitarijada 1967. They also appeared in movies: "Kad budem mrtav i beo" (When I'm Dead And White) and "Visnja Na Tasmajdanu" (Visnja In Tasmajdan). They recorded many songs that were used for radio and tv only - some are really great 60s punk killers.
