My guest this week describes music as ‘a portable environment’. His work patterns have taken him all over the world and he might find himself writing anywhere from a station waiting room to a hotel lobby or a scorching beach. No matter where he finds himself, the music will put him back where he left off. Perhaps unsurprisingly, his novels explore people who are lost, displaced or caught between cultures and he finds their soundtracks in the work of contemporary classical composers (including one of my own favourites, Olafur Arnalds). He is Toni Davidson and he’s on the Red Blog with his Undercover Soundtrack.
