For the past eight years, Audible, the audiobook behemoth, has joined forces with the Minetta Lane Theatre to produce staged plays that are recorded and eventually made available as streaming audio “originals.” Given that history, their latest collaboration, Jamie Armitage’s A Ghost in Your Ear, is extremely on brand. This 90-minute haunting is set in a sound studio, most of the action involves the recording of an audiobook, and audience members listen to the tale via headphones. If the frights are milder than one might hope, the work surprisingly has something to say about the travails of fatherhood, while unintentionally delivering important lessons on the nature of live performance.
