The Voyager Golden Record was packed off to space with plenty of a cappella, not least this lovely sounding polyphony performed by the Mbuti of the Ituri Rainforest in the Democratic Republic of Congo, circa 1951. I wanted to choose something made solely by human vocal cords, so I picked this minute-and-a-half of goose-bump raising awesome from David Francey.
