The drums on "Crossing the Triangle of Flames" are cool but nothing that really makes me excited, the cymbal work is nice though. Drumming on "Obsolete Tears" is better and more akin to the repetition method I mentioned, which I appreciate.
Fenriz drumming-wise was at his best on Soulside Journey IMO, just a hurricane of cymbals and fills that gives me goosebumps at times. He was also very interesting on Goatlord, just all over the place stylistically in a really cool way.
Ever since A Blaze in the Northern Sky which has some of his leftover death metal chops here and there his obsession with primitive simplicity has made his drumming less and less interesting for me, even though as a band I've liked their stuff consistently. Black metal isn't really rich soil for great drumming, unless the band is unorthodox within the genre.
This is so fucking good, Fenriz was once a madman:
