With apologies to Monty Python, "And now for something completely different" could just as easily describe every season of Quantum Theatre, which tackles idiosyncratic projects staged in unusual places.

"Quantum is an incubator for the amazing," says founder and artistic director Karla Boos, "rededicated each year with the rites of spring." So at a gathering for press and patrons this evening in Mellon Park, Quantum will unveil a 2008-09 season that includes a seldom done Shakespeare; a world premiere of a devised piece by British auteur-director Dan Jemmett based on unpublished work by a celebrated author; a poetic folktale by Lorca; and a prize-winning English comedy.

Even more to the Quantum point, these will variously involve the Robotics Institute at Carnegie Mellon University, overlapping audience seatings, flamenco, the outdoor rose garden at Mellon Park, the Frick Art Museum and other sites not yet determined. "We find it meaningful to place the audience and performers together, the moving parts inside the works," Boos says.

For Boos, constructing a season is also all about "bringing unusual kinds of artists into our mix." That certainly describes the Robotics Institute, contributors to the production of Shakespeare's "Cymbeline" (July 31-Aug. 24). It will open Quantum's new season in an old place, the Jennie King Mellon Rose Garden.

Quantum has used that space twice before, but Boos says it will be used differently and praises the flexibility of the city parks department. She won't reveal in advance how robotics will enter the play, but promises something unusual, since, "my idea of robotics is broader after drinking beer with these guys."

She cites Woody Allen's sex machine in "Sleeper," which relates to an automatic quality she finds in Shakespeare's late romance. "It's such a silly play, so cynically full of plot twists," but they all finally melt away in its astonishing final scene of redemptive revelation after revelation.

Jemmett's new work, "The Museum of Desire" (Nov. 6-23), will be based on two unpublished short stories, one of that name and "Flowers in a Corner," by John Berger, whom Quantum describes as "elder statesman of the art world," author of the art-critical "Ways of Seeing" and the Booker Prize-winning novel, "G." Jemmett visited Berger on the French mountain where he lives and came away with the stage rights.

Berger says that London's Wallace Collection was his inspiration for "Museum of Desire." Coincidentally, Henry Clay Frick built his art collection in emulation of the Wallace, so it's doubly appropriate that the play will be staged at the Frick in Point Breeze. As collaborators, Jemmett is reuniting "404 Strand," the same cast of five, including Rick Kemp, with whom Jemmett worked on his previous "Billy the Kid" for Quantum.

Quantum describes Lorca's "Yerma" (Jan. 29-Feb. 22, 2009, place to be announced) as "a deeply musical folktale, blending song and poetic text into a modern story of unbridled yearning." Melanie Dreyer will direct, and Carolina Loyola-Garcia, the flamenco dancer who enlivened Quantum's 2007 "Red Shoes," will collaborate.

Kevin Elyot's "Mouth to Mouth" (April 2-26, place to be announced) is a dark comedy about intimacy and betrayal that debuted at London's Royal Court Theatre. Elyot previously won awards with another acerbic tragi-comedy, "My Night With Reg."
