Our latest guest on Soundtracking has scored one of films that has most profoundly affected Edith in recent years, such is the gravity of the subject matter. 20 Days in Mariupol is genuinely harrowing, but also genuinely necessary and important documentary, charting in quite heart-wronching fashion the besieging of the Ukrainian city during the Russian invasion. Jordan Dykstra composed the music for the film, and we're thrilled he took the time to talk to us.
