MacLeod's description:

Genre: Unclassifiable
Length: 2:58
Instruments: Percussion, Horn, Misc
Tempo: 93

A thumping bass note intermingles with metallic noises to create a feeling of tension and terror. Screeching synth noises enter occasionally, and after a shrill screaming lead, the percussion is sparse but nerve-racking. 035
