Stockholm quintet Opeth have been gradually opening up their sound, inching away from deathmetal terror and toward old-school prog rock. On Heritage, they could almost be a jazz-fusion band conjured up by a Renaissance-faire magician. They exhibit unexpected energy and rhythm – "Slither" charges forward with the most optimistic overdrive they have ever allowed themselves. Add flutes, Middle Eastern percussion and Celtic- and flamenco-specked guitar beauty, and you have a career record that reimagines prog as actual rock & roll, even while portentously insisting, "God is dead."
