One of my earliest Undercover Soundtrack guests returns this week with a brand-new novel – and another beguiling musical journey. The story features a character whose life spans two timelines, which she envisaged in her head as having a soundtrack of two personalities. Aggressive guitar, driving percussion – softened by the melancholy lyricism of early Celtic folk songs. But she’d never heard such a thing in real life – until a chance listen one day expressed exactly what she’d been looking for. She is KM Weiland and she’ll be here on Wednesday talking about the Undercover Soundtrack for her newest release, Dreamlander.
