In Reading Stephen Sondheim: A Collection of Critical Essays, editor Sandor Goodhart interrogates an incongruity between Stephen Sondheim's reputation as one of the most important artists of the musical stage and the simultaneous paucity of serious academic attention to his work.
A nice collection of critical essays on the work of Sondheim. Despite Sondheim being the most important name in musical theatre in the second half of the 20th century, the amount of serious academic writing on his work is surprisingly paltry. It was on this basis that the essays in this book were compiled. The essays are very well argued and every author clearly has a, forgive the pun, passion for Sondheim. This is probably the closest we're going to get to a Cambridge Companion to Sondheim, at least for now.
