Reading a book is a solitary, intimate experience in which the reader sets the pace and imagines the characters as he or she sees them. Listening to a book is another way to appreciate a work, sometimes influenced by the narrator’s voice. Gatz, as created by Elevator Repair Service, uses an unprecedented approach, staging the book as it is read in its entirely. The performance begins when an anonymous office worker sits at a desk in a grungy office and, while waiting for his computer to boot, idly picks up The Great Gatsby and starts reading it aloud. The worker slowly takes on the character of Nick Carraway, the narrator of F. Scott Fitzgerald’s classic Jazz Age novel, who reads every word of the book including the “he/she saids” for a marathon six hours. Bit by bit, the other office workers assume the rest of the characters although the bulk of the effort falls to the staggeringly good Scott Shepherd.
