2002. I had heard quite a lot of Metallica and other metal bands before that, but I didn't like it much at all. Extreme metal, however, appealed to me. The records that got me into extreme metal were Dimmu Borgir - Enthrone Darkness Triumphant, Borknagar's "The Archaic Course", "Quintessence" and "Empiricism", Satyricon - Dark Medieval Times, Aeternus - .... And So The Night Became and Mayhem - De Mysteriis Dom Sathanas.
