What is the author's style in Krapp's Last Tape by Samuel Beckett?

Like all of Beckett's work, Krapp's Last Tape may strike the first-time viewer as odd and unsettling: there is a minimal set, no dramatic lighting cues, nothing that a theatergoer would call a traditional "plot," and only one character a character whose only conversations are with a tape recording of himself that he made thirty years ago. According to critic Roger Burstein, in using this style, Beckett was able to capture the futility of Krapp's dreams of himself as an artist. To Burstein, Krapp is a balance of "pathos and absurdity" that reveals the "vacuity" of our human desire to achieve greatness.
