Satyricon is a Norwegian black metal band formed in Oslo in 1991. Satyr and Frost have been the band's core members since 1993. The band's first three albums typify the Norwegian black metal style. Since its fourth album in 1999, the band has strayed from this style and included elements of traditional heavy metal in their sound. Satyricon was the first Norwegian black metal band to join a multi-national record label (EMI).
