Touchstone Theatre is known for its creative approach to theater.

Ever since the coronavirus (COVID-19) pandemic, the Bethlehem troupe has innovated through live-streaming, outdoor performances and film.

Now Touchstone is using the United States Postal Service to deliver theater.

Touchstone’s latest original production, “Letters from Far,” lands in mailboxes Feb. 15 through March 15.

The science-fiction story is told through four packages mailed in successive weeks to audiences. The story of a lost expedition in the future unfolds with each missive.

“We knew that early 2021 was going to be a challenge, given that it’ll be awhile before the weather’s suitable for performing outside again,” says Emma Ackerman, Touchstone Ensemble Member and writer and director of “Letters from Far.”

“And so, we wanted to create content that people could enjoy safely in their own homes, while still experiencing theater in inventive ways,” Ackerman says.

It’s 2032 and the Rosensweig Expedition has been sent to explore a mysterious rift found in the American Midwest.

The expedition of scientists, journalists and artists catalogue and report on what they find on the other side of the rift.

When the expedition does not return, all that remains are the packages they sent home, including letters, drawings and artifacts.

Audience members will get to read the final account of the party and piece together the last days of the journey.

“I always love a good sci-fi story, and with this project, we wanted to use that lens to focus on the ways we try to communicate the impossible to one another,” says Ackerman.

“In an era where so many of us are operating in different spheres of information and seemingly different realities, this theme feels all the more worthwhile to explore,” Ackerman says.

Touchstone Theatre hosts “Pie,” a livestream performance by Theater Grottesco, 8 p.m. Feb. 5.

The theater group from Santa Fe, N.M., will perform its award-winning comedic exploration of the unknown, featuring a panel of clowns and a “reset of the universe.”

The play begins as four armchair experts arrive at a panel discussion, only to find that the moderator is a no-show.

As tensions rise, a Rube Goldberg-like chain of accidents slowly tips. The characters have a collective emotional breakdown and accidentally hit the restart button on the universe.

A skewed history of reality follows, from moments before the Big Bang until today. The play’s title is derived from the Carl Sagan quote, “If you wish to make an apple pie from scratch, you must first invent the universe.”

The play is a 2017 National Theatre Project Award Winner.

The streamed performance is followed by a live broadcast of a talkback session with ensemble members from Grottesco.
