BBC: "Sunn O))) (their name is that of a vintage amp) play doom metal of a monolithic power and almost apocalyptic intensity, using waves of loud, hypnotic drone, overlapping, feedback-affected chords held for what seems like an eternity, and layer upon layer of sludgy, psych-rock soundscapes. They’ve sacrificed the traditional elements of rock – melody, harmony, song structure – in favour of improvisational freedom and, in many ways, have more in common with minimalist composers like Steve Reich than, say, the black-metal fraternity."
