Epic45's latest EP is an attempt to sonically recreate the experience of exploring Drakelow, an underground complex built in rural England during the 1940s to serve as government facilities and shelters in case nuclear war broke out. The facilities are now abandoned and forgotten by most, with much of it cordoned off by the government for safety reasons. But parts of it are still open for exploration, and so two members of Epic45, along with members of Ruraline and July Skies, descended into the tunnels last year.
