I find it so interesting how one novel’s soundtrack can absorb so many styles. My guest this week has written a supernatural mystery wrapped up in a 1920s comedy of manners and her soundtrack is a glorious tour of classical, folk and madcap jazz. Even more interesting, she uses Thomas Tallis – as my guest did last week – but with such a different outcome. We all operate in our own key of creativity, which is one of the wonders of this series for me. Anyway, this week you can enter the classical, folky and knock-bones skelly-shaking jazzy world of Alice Degan – with her Undercover Soundtrack on the Red Blog.
