Гробъ or translated in English: Grave is a Bulgarian black metal act and Oblivion is their first album that Funeral Hymns Records has released on limited to 60 pro- cassettes.
Ripping riffs and screams well mixed with clean singing and even female vocals evolve the atmosphere in the album to a special emotional level.
The music is in the vein of the old Dimmu Borgir and Borknagar's albums.
Here is one of the songs in the album: https://www.youtube.com/watch?v=FNcVmqg8f18
