Categorizing Sunn O))) as drone/doom metal is only really appropriate when the duo are at the peak of their Earth-tribute mode. This was very much in evidence last night at Sonar, where at least half the band's 90-minute set was more like avant-garde noise played really, really loud. Sunn O))) can be a bit inscrutable, but their live show is a beast of glacial proportions: fog so thick one can barely see fellow audience members, much less the performers on stage; hellish red light outlining black-robed band members; and, of course, so much sound that it is a physical presence in the room.
