Sunn O))) - Trivia

White2 features Attila Csihar (Mayhem) quoting the Srimad Bhagavatam on "Decay2 [Nihils' Maw]".
"F.W.T.B.T." is an interpretation of Metallica's "For Whom The Bell Tolls". While the band did try to follow the original structure and riffing of the song, the intent was not to copy the original, but to rewrite the song for themselves.

The full title of the cover is "F.W.T.B.T. (I Dream Of Lars Ulrich Being Thrown Through The Bus Window Instead Of My Mystikal Master Kliff Burton)".
Black One is a combination of both experimental and traditional Sunn O))), utilizing many guest musicians, including black metal musicians Malefic (Xasthur) and Wrest (Leviathan), respectively. The band supposedly also went so far as to lock the claustrophobic Malefic in a casket to record the vocals on "Báthory Erzsébet".
Sunn O))) is named after the Sunn amplifier brand, whose logo includes a circle next to the "SUNN" banner with waves heading off to the right (the band uses this logo in the cover art of many releases).
