[Intro - Unaccompanied Children's Choir] [ONLY young children's voices. Slow original Christmas-like sacred hymn in a cold, mournful minor mode. Very quiet, fragile and pure. Sing a clear repeating melody with gentle harmonies. NO INSTRUMENTS. NO GUITARS. NO DRUMS.] Mmm... Ooh... Ah... Ooh... Mmm... Ah... Ooh... Ah... [Children's Hymn Reprise] [Continue the SAME unaccompanied hymn. Extend the melody with sustained high notes. Preserve the innocent children's voices. Still absolutely no instrumental accompaniment.] Mmm... Ooh... Ah... Ooh... Mmm... Ah... Ooh... Ah... [The World Begins to Collapse] [Keep the children's hymn singing. A faint low-frequency rumble and distant dissonant texture slowly creep in. The background becomes increasingly threatening. NO ELECTRIC GUITARS OR DRUM KIT.] Ooh... Ah... Ooh... [Siren Emerges] [A barely audible air-raid siren fades in beneath a single child's prolonged cry-like vowel. The siren gradually becomes louder and higher. The child's voice and siren merge into one disturbing sustained sound. Choir fades away. The siren completely takes over. NO METAL INSTRUMENTS YET.] Ahhhhhhhhh... [Shell Impact] [ONE IMMENSE EXPLOSIVE IMPACT. Instantly cut every sound.] [Dead Silence] [Complete silence. No instruments, no ambience, no reverb. Hold the silence before the next section.] [PART TWO - INSTRUMENTAL THRASH METAL] [192 BPM. INSTANT AND VIOLENT FULL BAND ENTRANCE. The choir is GONE. No transition melody. Raw aggressive electric guitars, double-kick drums and bass strike together.] [Thrash Riff A] [Relentless downpicked palm-muted sixteenth-note guitar riff. Tight bass unison, rapid double-kick, dry cracking snare. Dark chromatic movement. Violent precision.] [Thrash Riff B] [Switch to a faster, jagged riff with dissonant semitone movement, galloping rhythms and sudden synchronized stops. No clean singing, no choir.] [Thrash Riff C] [Heavy syncopated guitar and bass strikes. Sudden half-time drum accents while guitars continue fast subdivisions. Abrupt rhythmic cuts followed by full-band attacks.] [Final Thrash Assault] [Return to maximum intensity. Combine earlier riff motifs with relentless double-kick and aggressive downpicking. No orchestral layers. No choir. No melodic resolution.] [Final Hit] [One synchronized full-band strike. Immediate silence.]
