Distant plucks ring out over dark beds of drones, and an insistent, driven pulse.

Ever-building tension, with breathing pulses and clashing drones.

Persistent pulses, unsettling drones and a menacing bass, with a constant tick against the clock.

A menacing bass pulse, with skittering percussive taps and haunting drones.

Building pulses drive over gritty drones and distant electronic wails.

Nervous drones ring out beneath a cold piano, shifting pulses, and distant percussive taps.
