Polish bands usually play something quite satanic, influenced by Morbid Angel, and quite fucking brutal when it's about Death metal... But this one is much closer to the Swedish style. The two tracks you hear are close to the first ENTOMBED and first GRAVE albums, with few heavier parts à la UNLEASHED ("Where no life dwells"). The second song also has a bit of "You'll never see..." (Heaviness) and reminds me a bit of the first ILLDISPOSED album (Some blasts, some 1/2 1/2 beats). Peoples who liked newer bands like BASTARD PRIEST (Minus the punk influence) or MIASMAL (Demo) could like MORT DOUCE because it's the same kind of Swedish DM rendering (With some heaviness and no thrashing). It's a pretty solid sounding short demo, but it might lack a bit of juice or ejaculating nightmare over the top of the cadaver cake. Future will show us how their sound will evolve. Now I'm not sure what they meant with "Mort douce", in French it stands for "Soft death" or "sweet death".
