Renowned opera diva Maria Callas is teaching a master class in front of an audience - us! She's glamorous, larger than life--and drop-dead funny. An accompanist sits at the piano. But before a student can sing a note, Callas takes center stage. What begins as a class becomes an intimate and revealing look into her life: we learn about Callas' tumultuous affair with Aristotle Onassis, her early days as an ugly duckling; the fierce hatred of her rivals; and the unforgiving press that savaged her at first. A riveting play that includes the beautiful arias that made Callas an international diva of epic proportion, Master Class is a tour-de-force lesson underscored by simple truths about life and art.
