MacLeod's description:

Genre: Soundtrack
Length: 0:50
Instruments: Bass, Percussion, Strings
Tempo: 116

This short piece is the accompaniment for the hero surreptitiously breaking into a corporation or headquarters. The reverberating congas, triangle, and synthesized percussion enhance the senses, while the bass guitar provides a strong groove. The strings raise in pitch, evoking a sense of building tension. High-pitched crescendo of strings at 0:45 is the climax of the suspense. 039
