My guest this week is tackling the Croatian conflict of the early 1990s, and she used music to suggest fragments, atmospheres and moments of memory. When she sent me her post, she remarked that she found the process of writing it had been even more challenging than the novel, as she had never before admitted anyone to her personal space of creativity. This is one of the reasons I’m continually refreshed by this series – no matter what genre the book is, or what type of music they choose, the heart of each post is this real contact with a writer delving for the truth. Anyway, here you’ll find some haunting and unusual pieces by PJ Harvey, Smoke Fairies, Steven R Smith and Laurie Anderson, all in the Undercover Soundtrack of Alison Layland – airing here on Wednesday.
