Radio drama is a dramatized, purely acoustic performance. With no visual component, radio drama depends on dialogue, music and sound effects to help the listener imagine the characters and story: "It is auditory in the physical dimension but equally powerful as a visual force in the psychological dimension." Radio drama includes plays specifically written for radio, docudrama, dramatized works of fiction, as well as plays originally written for the theatre, including musical theatre, and opera.

Sir William Tyrone Guthrie was an English theatrical director instrumental in the founding of the Stratford Festival of Canada, the Guthrie Theater in Minneapolis, Minnesota, and the Tyrone Guthrie Centre at his family's ancestral home, Annaghmakerrig, near Newbliss in County Monaghan, Ireland. He is famous for his original approach to Shakespearean and modern drama.
