Salman Rushdie gained fame and infamy for his 1988 novel, The Satanic Verses. The NPR story about his latest book Joseph Anton is told in the form of an interview. The story alternates between the interviewer and Rushdie, the latter’s voice making up the bulk of the sound clips.
Beyond voice, there is little sound otherwise. Silence, a lack of sound, is used here too. This minimalism in the sound creates an effect. Rushdie is speaking about his life in hiding. The lack of sound seems to magnify his voice. This is a good use of sound because it is used sparingly, allowing the listener to focus on the story.
