The mainstage season follows:

The Babylon Line
By Richard Greenberg
Directed by Terry Kinney
June 25-July 6
"1967. A 38-year-old writer from bohemian Greenwich Village commutes to Levittown, Long Island to teach an adult-education Creative Writing class. He finds anything but the cookie-cutter lives he expected in this straight-laced community, as his students come to discover the power of storytelling to transform their lives. And one special student – a kindred spirit? or something more? – reawakens him to his own artistic impulses." In Your Arms
Directed and choreographed by Christopher Gattelli
Music by Stephen Flaherty
Vignettes written by Douglas Carter Beane, Nilo Cruz, Christopher Durang, Carrie Fisher, David Henry Hwang, Rajiv Joseph, Terrence McNally, Marsha Norman, Lynn Nottage and Alfred Uhry
July 5-13
"In Your Arms features ten dance vignettes—written by a unprecedented collection of preeminent playwrights—that each tell a story without words of a pair of lovers, constituting an evening of storytelling, dance and music with a cast of more than 20 performers."

The Listener
Written and directed by John Patrick Shanley
July 16-27
"The Listener is a mystery which unfolds against an international backdrop. The main character, a female insurance investigator, finds herself battling wits with a formidable Danish widow. Disturbing, funny, deadly serious, sexy, like a Hitchcock film with a modernist edge."

Musical workshops:

SeaWife
By Seth Moore and The Lobbyists
Directed by and developed with Liz Carlson
Performances June 27–29 in The Susan Stein Shiva Theater
"Supernatural characters, romance, tragedy and stirring original music by The Lobbyists combine in this one-of-a-kind event – part play, part concert, and part immersive experience. We follow Percy, a young sailor bred in the golden age of the American whaling boom, as he journeys through port cities and wrestles with ghosts, sea monsters, and the loss of his one true love."

A Walk on the Moon
Music and lyrics by Paul Scott Goodman
Book and additional lyrics by Pamela Gray
Directed by Michael Greif
Performances July 25–27 in The Vogelstein Center for Drama and Film
"It's the summer of 1969 in a Catskill Mountains bungalow colony. While her husband spends each week working in the city, Pearl Kantrowitz finds herself drawn toward a free-spirited traveling salesman. Her personal crisis plays out against one of America’s most tumultuous summers, as astronauts walk on the moon, the Vietnam War escalates, and Woodstock takes place right down the road. Michael Greif, the award-winning director of Rent, Grey Gardens and Next To Normal, returns to Powerhouse with this deeply romantic story of awakening, adapted from the hit film."

Play workshops:

The Light Years
Written by Hannah Bos and Paul Thureen
Developed and directed by Oliver Butler
Performances July 11–13 in The Susan Stein Shiva Theater
"From The Debate Society, a haunted love story spanning four decades. Chicago 1893: The Zoopraxiscope, cracker jacks and neon lights. The Ferris Wheel, hootchy-kootchy... hell they even had the hamburger! On the eve of a glowing new century, something terrible happens in a humble two-story home. And everything ends. Chicago 1933: When the fair returns 40 years later, so do the unfinished histories of everything that could have been. And so things begin for the hermit upstairs and the mysterious look-a-like below."

Laugh
By Beth Henley
Directed by David Schweizer
Performances July 18–20 in The Susan Stein Shiva Theater
"Mabel's had a hard few weeks: A dynamite accident at a gold mine has left her wealthy but orphaned, and she’s shipped off to a scheming aunt and a long-lost cousin, who’s charged with seducing her to control Mabel’s fortune. This hapless courtship reveals a shared love of silent movies and a plan for greater things. A story of mishaps and moxie, the romance of Hollywood and ultimately a Hollywood-caliber romance. A slapstick comedy from the Pulitzer Prize-winning playwright of Crimes of the Heart and The Jacksonian."

New plays by Winnie Holzman, Stephen Karam, David Rabe and Ayad Akhtar have been selected as part of the Play Readings Festival, which will be presented this summer during New York Stage and Film's Powerhouse Theatre Season.
