Probably THE polish top Heavy Metal single ever. DEEF had released another 7" one year earlier containing nice Heavy Rock, but on this one they've turned into first class Heavy Metal. The track "Zaczyna sie" let KAT looking like average farts, a top notch Power/Speed Metal hammer that's making you wanna cum again and again. The aggression and power that this songs is spreading seems to be sheer endless. Though the flip side track is softer, more melodic Heavy Metal but not less listenable - the opposite to the outstanding A-side. 2 essential Metal trax from eastern Europe and belongs to any Metal vinyl collection.
