Exhumator (Bul) - Аз Нося Смърт 1992, probably doesn't fit in 100%, but the songs were written in 1987-1990, some of them previously released on several demo/reh tapes when the band was called Diktator. A proper madman's music sound, maybe bulgarias Exmortes? But a lot more capable at writing & performing songs, very obscure black/death/thrash metal, at times reminding me of the more evil/early Korrozia Metalla songs.
Exorcist (Pol) - Voices from the Graves 1987, twisted black thrash/speed with a slightly medlodic note, very very good stuff (Pile Driver is totally nuts)! The band reunited pretty recently and is working on the new album as well as a demo material compilation.
