Sunn O))) and Ulver are no strangers to collaboration in the fringes of extreme metal, but I’m surprised that the two haven’t gotten together for a full-fledged collaborative album in the past! The two seem like a natural fit despite their markedly different sounds, and with Ulver’s ambient weirdness and Sunn O)))’s penchant for sustained chords and monstrous feedback, it should make for an interesting sound.
For an idea of what to expect, here’s ‘CUTWOODeD’ from Sunn O)))’s 2006 White album, featuring Ulver.
Terrestrials is sure to be a fascinating listen. There aren’t any details available just yet, but keep an eye out for it in 2014.
