Swan first encountered Mackenzie in 1988 when she was performing traditional Gaelic tunes at a concert in a village hall in South Uist. He persuaded her to collaborate with him on a new project fusing Gaelic music with contemporary technology and a developing world music sensibility (at least partially inspired by Fourth World music experiments such as David Byrne and Brian Eno's 1981 album "My Life in the Bush of Ghosts"). Working with arranger and engineer Chic Medley, the duo began to record together. Mackenzie brought in most of the early Mouth Music repertoire in the shape of traditional Gaelic songs which she had discovered while studying Scottish and Gaelic cultures in Edinburgh.
