Carach Angren is a symphonic black metal band from the Netherlands, formed by two members of Vaultage. Their style is characterised by prominent use of orchestral arrangements. All of their studio albums are concept albums with lyrics based on famous ghost stories, such as the Flying Dutchman. The name means "Iron Jaws" in the language of Sindarin, and is the name of a fortified pass into North-Western Mordor in J. R. R. Tolkien's The Lord of the Rings.
Vildhjarta is a thall metal band from Hudiksvall, Sweden, formed in 2005. Their musical genre as described by themselves is "ambidjent". It has taken them a few years to go from something abstract into something concrete. However, their music is a mixture of the abstract and the concrete. The ambient and peaceful moments find a stark contrast in the more brutal and dark music that combined contribute to the comprehensive style of Vildhjarta.
