Our definition of drone has continued to expand, and now includes everything from steady hum to walls of sound, from cello drone to factory noise. Sustain and decay are typical elements, as emphasized in Owen Coggins’ book of the same name. Psychedelica and mysticism may be present, as visited by Harry Sword in Monolithic Undertow. Even thunderstorms and electrical wires can produce their own brand of drone, as illustrated by SELVEDGE‘s cover image. Drone labels have also broadened their horizons, releasing works that inhabit the porous borders between drone, ambient, metal and more.
