‘A Delicate Balance’

Playwright Edward Albee penned “A Delicate Balance” in the 1960s and it won the Pulitzer Prize for Drama. Mad Horse Theatre Company’s production is directed by company member Christopher Price. The story centers on the ill-at-ease lives of upper-middle class suburbanites Anges and Tobias, along with their houseguest Claire, Agnes’ funny, alcoholic sister. Their lives are derailed when longtime friends Harry and Edna seek refuge from a mysterious terror, and are subsequently joined by their cranky daughter Julia, on the heels of her fourth divorce.

“A Delicate Balance” is a riveting study of family dynamics and drama. Catch the Friday night show this week and stay for the aftershow party with the cast, creative team and company members.

Maddie Imus portrays the title character of Amethyst, who gives her heart to a sailor and winds up wondering about humanity and what kindness means. With elements of horror and fake blood, it’s recommended that viewers be at least 8 years old.
