The lyrics on this contemporary alt-pop album from Gwenno Saunders are almost entirely in Cornish, except for one song in Welsh, NYCAW, which stands for Nid yw Cymru ar Werth (Wales Is Not for Sale), a famous slogan from the 1990s reinvented into a broadside against neoliberal cultural genocide. Saunders grew up in Cardiff with a Welsh-speaking mother and Cornish-speaking father — the poet, journalist, and linguist Tim Saunders. After a slightly incongruous stint with Michael Flatley’s The Lord of the Dance, she became a member of a moderately successful retro pop band called The Pipettes alongside her sister, Ari. Saunders’s third solo album, Tresor, is another riveting addition to a colourful career. The title is the Cornish word for “treasure” and has nothing to do with the Berlin-based techno label of the same name. Tresor explores the impact of motherhood on her psyche, but also dives deep into pertinent themes such as technological alienation on Y Dydd Olaf (The Final Day), and meditations on home and identity on Le Kov (The Place of Memory). Gwenno’s blending of pastoral folk with adventurous ambient electronica is delightful, creating an innovative album that isn’t afraid to address big ideas through the medium of a marginalised Celtic language. Tresor truly is a landmark album from a fascinating artist.
