One of the most iconic stems is the vocal percussion track. Michael Jackson recorded himself snapping his fingers, patting his chest, and making a "shu-shu" sound with his mouth. In the mix, this sits subtly under the snare to give the groove a human, organic swing. Isolated, it sounds like a ghost whispering the rhythm.
When it came time to record the final version, Jackson, Swedien, and Jones went all out.
