A wild and eclectic sound best described as Avant-Garde Symphonic Black Metal (or something of the sort), has a chaotic sound but is more structured than Unexpect, though I see certain similarities at points. However, this band delivers extreme metal with an avant-garde and symphonic twist at times. The Serpent's Manifold (their newest full-length) is ominous and eerie at points and heavy without being overly oppressive. Well, my descriptions may be different from what you hear, so just take a listen (especially you, Knight, I think you'll like this band)
