On Watershed, Opeths stately soundtracks for snow-flecked forests feel more spacious and majestic than ever. Setting oboe against pipe organ and blues-rock solos against madrigal harmonies, warming their placid acoustic opener with a wood-nymphs warble, letting nimble Celtic strumming evolve through ferocious horror-ogre thrash into an extended minimalist swirl, Opeth specialize in an eclecticism so ambitious youre shocked it doesnt topple over. Fancy drumming, I Am the Walrus cackles and track-lengths averaging eight minutes are ominous echoes of prog-rock excess. But prog was rarely as songful as the brutal beauty here.
