Sand, Silt, Flint is a fascinating ballad map of north-eastern Scotland by Scottish-Burmese singer, writer and producer Fiona Soe Paing, who has performed in all-female punk bands, released a bilingual album about heritage and identity, and experimented wildly with vocal improvisation. She recently discovered she was related through her mother to Aberdeenshire bothy ballad singer John Strachan, which deepened her fascination with local songs. She then turned to electronic textures and atmospheres to conjure vivid impressions of their settings and landscapes.
