Unity Theatre presents, Master Class, by Terrence McNally.  Winner of the 1996 Tony Award and Drama Desk Award for Best Play, Master Class is hilarious, moving, and untimately riveting.  In a 1971 Juilliard School classroom, three aspiring voice students meet the celebrated opera diva, Maria Callas, now past her prime.  The play goes beyond portraying the life of Maria Callas.  It explores the heart of a creative passion that connects life to art, and the immense self-sacrifice that great art so often requires.
