Gwenifer Raymond has a PhD in astrophysics, lives in Brighton and designs video games for a living. No ordinary human, she also has mercury in her fingertips. You can just about see it glisten as she plays guitar on There Will Be Blood for an introductory 2016 acoustic session. By early 2018, the song had evolved into Sometimes There’s Blood, and a video treatment with creepy Victoriana and taxidermy. Such is the Welsh-born Raymond’s very British take on a niche form known as the American primitive style, where guitars embark on flowing instrumental extemporisations, often ending up somewhere very eastern, sometimes sounding like Indian ragas. Having discovered the guitar aged eight, when her mother gave her a cassette of Nirvana’s Nevermind, Raymond traced the idols of her idols back to the Delta blues, and then sideways into this folk form. Her immersive debut album pays tribute to the Delta and Appalachia at the same time, on the banjo workouts Bleeding Finger Blues and Idumea, and raisesa a battered hat to the godfather of the primitive scene on Requiem for John Fahey. Throughout, Raymond takes this roiling, rhythmic traditional sound and stamps her own imprimatur on it.
