Imagine: Abbath and Alex von Meilenwald, hiking the Arizona desert, get lost in an Indian burial ground. To survive, they subsist on peyote-laced buffalo chips dropped by Vrolok and UFOmammut. The result: a spiritual testament slouching between ambient, black, and doom metals, casting Native American iconography alongside Futhark runes. Several tracks are mercilessly plodding, and some listeners may find the naturist atmosphere affected, but 'A Feral Spirit' is admirably thorough (the pipes are also an effective touch). Its chief failure is sustaining momentum, without which BotBO will never be relevant to more than the smallest cult crowd.
