Kjetil-Vidar Haraldstad
Norwegian musician

Kjetil-Vidar Haraldstad (stage name Frost; born 28 June 1973) is a Norwegian drummer in the black metal bands Satyricon and 1349. He was born in Øyer Municipality in Oppland county.
Frost has previously performed with Gorgoroth, Zyklon-B, Gehenna and Keep of Kalessin. He originally joined Satyricon temporarily to record the demo The Forest is My Throne, later joining the band full-time. He has a degree in Engineering, having taken a course in Computer Science at the University of Oslo.
He is regarded as one of the fastest and most proficient drummers in the black metal and extreme metal genres. Frost employs various drumming styles when performing with different bands; in 1349 and early Satyricon he extensively uses blast beats, with his most recent work in Satyricon being more thought-out and mid-tempo. On 1349's 2009 studio album Revelations of the Black Flame he played at a slower speed as it was a more experimental album, but for every other release by the band he has consistently played at higher speeds. On all Satyricon albums his role is credited simply as "battery".
Frost was denied entry to North America by the US Department of Homeland Security upon failing to note his having been sentenced to 5 months in jail for assault (during a bar fight in the early '90s) when applying for his work visa.

Why this record matters
The phrase “norwegian musician” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q359355. VIAF identifies the subject as 315944501. The Library of Congress control number is no2015060330. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1973, 1349 and 2009.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
