Limited two CD edition includes bonus disc of instrumentals. 2023 release. Musically, Fauna represents Haken at their most diverse. Taurus commences the album with it's scraping heavy metal chords, as polyrhythmic as they are jagged. However, Ross's melodic croon and the triumphant chorus are true Haken. Eyes Of Ebony is pure math rock, delicate in it's start-stop clean guitar picking and chiming cymbals, while Island In The Clouds flaunts it's bouncing bassline. Eighteen years deep, they're still evolving and keeping their fans on their toes. Is there any truer definition of what making progressive rock means than that?
