Ulver is an ever changing band stylistically, wether it be horridly produced Black Metal, to Industrial or Folk, this band has done it. The only two noteworthy albums are Kveldssanger, which is acoustic folk, and Bergtatt, which is folk-metal along the lines of old Opeth. The vocals are half way between clean singing and gregorian chants. Sadly the band didn't realise that they were on to a good thing with these two albums, and have totally abandoned this style. If you see an Ulver album that is -NOT- called Kveldssanger or Bergtatt, then avoid it like the plague!
