Blažić was the group's frontman since its formation in 1977 until his death of Hodgkin lymphoma in 1987, recording seven studio albums and two live albums with the group.

Blažić was born on 8 April 1951 in Pula. He started his career as a singer in Pula rock band King Stones. At the beginning of the 1970s, Blažić (at the time playing the drums), vocalist Branko Umković, and three other future members of Atomsko Sklonište, bass guitarist Bruno Langer, guitarist Dragan Gužvan and drummer Saša Dadić, formed the cover band Hush. In 1974, Langer moved to the band Boomerang from Koper, where he was soon joined by Blažić, the two performing with the group until the autumn of 1976.

The band Atomsko Sklonište was formed in 1977 on the idea of poet Boško Obradović, who aspired to form a band which would perform songs featuring his anti-war lyrics. Blažić was the member of the band since its formation. The group attracted the attention of the public with their anti-war concept and cataclysmic imagery, and gained large mainstream popularity with the release of their debut album Ne cvikaj, generacijo (Don't Be Afraid, My Generation) in 1978. The group maintained their popularity with their live performances and following studio albums, scoring a number of hit songs. Blažić recorded seven studio albums with the band, including the English language album Space Generation for the foreign market, as well as two live albums. In 1985, he took part in the YU Rock Misija project, a Yugoslav contribution to Live Aid, contributing vocals to the song "Za milion godina". He had his last performance with the band on 21 July 1986 in the Pula club Uljanik.

Blažić has been suffering from Hodgkin's disease since 1971. He died as a result of his illness in Pula on 18 January 1987. It is reported that more than 4,000 people attended his funeral two days later, on 20 January.
