If my information is correct, Černý Kov is a collective of friends and the Circle of Souls fellowship, a Czechian movement that includes members of Maniac Butcher and Cult of Fire to mention some examples.
These songs are made between 2006 – 2018 and just recorded when felt like to record something. The Black Metal is raw and melodic and has the organic atmosphere that fits the description of how and when recorded. Capturing the mood shall we say…A song like “Noční úsvit” sounds evil (enhanced by the vocals), haunting and obsessed but they beauty of darkness captures you. Nice one! (Ricardo)
