Russian male choir with thunderous basses, martial folk-choral pulse and broad unison singing; verses march with low drone and measured handclaps, pre-chorus thins to deep bass hum and a single tenor lead, chorus opens into stacked men’s harmonies and stomping rhythm. Add antiphonal shouts, a brief a cappella lift before the last chorus, and ringing metallic accents between phrases. Wide, powerful, cathedral-bright mix with a granite-low end.
