Sunn O))) perform no-tempo dirge metal with zero drums and meditative levels of repetition. The band plays live at previously inconceivable volumes (for first-timers) while dressed in black cloaks and shrouded in the disorienting output of multiple fog machines. Main instigators Stephen O'Malley and Greg Anderson have performed together in Burning Witch and separately in Goatsnake (Anderson) and Khanate (O'Malley). With rare vocals and endless songs that feature subtle, practically subconscious melodic changes, Sunn O))) are generally considered the loudest and most challenging of the drone/doom metal scene. With six proper albums and twice that amount released in live material, splits and EPs, Sunn O))), while best experienced live (and with a lawn chair), manage to translate their holy sorcerer metal to vinyl with no drop-off in quality. That is, as long as you have good headphones or a sound system that can handle bass tone so low one wonders if man was ever really meant to hear them.
