In my opinion, the most powerful album of Grave Digger.
You can argue a long time about the cult of this or that album, personally I consider it to be Heart Of Darkness. Throughout the album, in my opinion, the darkest and even some disturbing atmosphere, although almost all of their songs do not shine with cheerfulness and serenity (which only one intro of Tears Of Madness is worth). A very powerful thing The Grave Dancer which, along with Circle Of Witches - are favorites on this opus. The cover is made traditionally superb and completely corresponds to the gloomy mood of the album. This gloominess is so serious and not faked that after listening you do not go into depression, but on the contrary, you get ready and become very serious...
