As someone deeply conscious of the mystery of time as the basic mode of being, the whole concept of recording sound and images — and thus, in a sense, making time repeatable, stopping it so that one can actually relive past time — fascinated him; hence the play Krapp’s Last Tape was his direct response to discovering tape recording, when the BBC sent him a tape of his earliest radio play [i.e., All that Fall].
