Heidi Harris works with a palette of folk and Americana pigments, but she doesn’t paint quite the pictures you might expect. Folk music is a collective aurality, the sonic expression of an orally transmitted tradition, and as such, it daubs its canvases with the colours of communal experience: even when it trades in specificities, perhaps the transportation of a loved one in punishment for a minor crime, it is a shared misfortune that is lamented, and it is its similarity to the experience of other participants in the music that is important.
