At the time of the band's formation, Swan (born in Sheffield, England, but of Scottish descent) was an Edinburgh-based composer, engineer and multi-instrumentalist with diverse musical interests including traditional Scottish folk, jazz, funk and electronic dance music. MacKenzie (born in New York) was a talented Scottish-American singer, pianist and ethnomusicologist who had taught herself Scottish Gaelic during her teen years. Conservatory-trained, her history and interests included teaching, Eastern European music and choral music: she had released a solo album called "Shantyman!" in 1986 (under the name of Talitha Nelson), had briefly been a member of the Boston-Irish band St James Gate and had toured America as a solo act or performing puirt a beul with Scottish traditional music bands. Having previously visited Scotland to make field recordings of folk music and research her own Scottish cultural heritage, MacKenzie moved to Scotland in 1987 and promptly joined the Scottish folk music ensemble Drumalban (in which she worked with unorthodox bagpipe and violin virtuoso Martyn Bennett).
