Personal information

Born on: 20.01.1972

Oscar Fredrick Dronjak (born January 20, 1972) is a guitarist of the heavy metal band Hammerfall. He is the only current member who was among the original line-up.

Dronjak was born in the Swedish town of Mölndal. His first instrument was the accordion; he then played trombone for a few years until, at the age of fourteen, he settled on guitar. Soon after, he started his first band, called the The Hippie Killers. In 1989 he started a death metal band called Desecrator, which was later renamed Ceremonial Oath. But just before they released their first album, he quit the band. The end of his career in Ceremonial Oath was the beginning of Hammerfall. At first, Hammerfall was merely a side project, and he and some friends were just rehearsing some songs that he had written, one of them being "Steel Meets Steel". But soon, they recorded their first album, called Glory to the Brave. Oscar uses Jackson guitars.

He also performed backing vocals for two In Flames albums: Subterranean (on the track "Stand Ablaze") and The Jester Race ("Dead Eternity").
