Deep reverberant ringing drone, cavern
Oscillating deep ringing drone
Dark, cave convolution drone
An experimental or surreal ambient drone or background.
Slow, swelling short-wave distortion pad.
Deep alien machine working, soft and subtle
Swirling metallic wave drone
Moaning whining children with small crowd in background.
Crowd murmuring, children, male and female voices
Exterior crowd walla. Large Spanish crowd.
