What's not to love about a band that combines polka music with black metal and has members named Beast Dominator and Trollhorn? The Finnish band Finntroll returns with their fifth studio album, and their first since 2004. Ur Jordens Djup, which translates to "From The Depths Of The Earth," also features new vocalist Vreth. The album is a little darker and heavier than some of their past releases, and combines intense heavy metal with Finnish polkas called "humppa." Finntroll moves easily between ominous, driving black metal and lighter, upbeat folk/polka. It's an interesting juxtaposition to hear acoustic and traditional instruments alongside aggressive, slashing guitars. Vreth fits right in with his vocals, which are harsh and raspy. The lyrics are once again in Swedish. Finntroll has a unique sound and style that's fun and melodic, but also has a sharp and cutting edge.
