This groundbreaking book is the first full-length study of British horror radio from the pioneering days of recording and broadcasting right through to the digital audio cultures of our own time. The book offers an historical, critical and theoretical exploration of horror radio and audio performance examining key areas such as writing, narrative, performance practice and reception throughout the history of that most unjustly neglected of popular art forms: radio drama and ‘spoken word’ auditory cultures. The volume draws on extensive archival research as well as insightful interviews with significant writers, producers and actors. The book offers detailed analysis of major radio series such as Appointment with Fear, The Man in Black, The Price of Fear and Fear on Four as well as one-off horror plays, comedy-horror and experimental uses of binaural and digital technology in producing uncanny audio.
