An Aisle Seat Review PICK! Quirky, Wonderful “Heisenberg” at Left Edge Theatre – by Barry Willis

A seemingly chance encounter between a mature London butcher and a younger woman prompts  unpredictable developments in Simon Stephens’s “Heisenberg,” at Santa Rosa’s Left Edge Theatre through February 2.

Directed by Carla Spindt, the two-actor, six-scene piece takes its name from German physicist Werner Heisenberg, whose famous “uncertainty principle” means, in its largest sense, that we can’t really be sure about what we think we know. It opens with Alex (John Craven) sitting calmly on a park bench when quite unbidden, Georgie (Shannon Rider) approaches and kisses him on the neck—the first time they’ve met. She introduces herself and gushes almost uncontrollably while he looks on befuddled—clearly this is a “red flag” moment but he plays along, listening attentively and politely without offering encouragement. 

It’s an extremely odd first encounter. In the second one, having done some minor detective work via Google, she’s tracked him down at his butcher shop, and comes on even stronger, this time with a completely different tale about who she is and why she’s interested in him. Amused and flattered by the unexpected attention, he’s again receptive but does not encourage. Craven maintains his character’s distance throughout, a mix of caution and curiosity, while the energetic Rider pours out ever-more-fanciful tales that culminate in a confession that she hasn’t seen her adult son in years and needs to go to America to find him.

. . . a fascinating dance, a true theatrical pas de deux.”

As the two become friendlier, her various veils of hyperactive identity fall away but it’s still never clear to Alex or the audience (or possibly to Georgie herself) which part of her is real and which is not—a maddening and very funny scenario. Having accepted that Georgie is off-kilter but probably harmless, Alex makes his peace with the situation’s unpredictability and goes along for what proves to be a lovely ride. It’s a fascinating dance, a true theatrical pas de deux.

Both of them veteran performers, Craven and Rider are fully committed to this delightfully ambiguous yet somehow totally believable piece of magical realism—Craven the embodiment of fascinated reticence, Rider a whirlwind of imaginative insistence. The drama and the comedy are equally enhanced by sound designer Joe Winkler’s lovely tango music and Chris Schloemp’s marvelous projections on an elegant set by Argo Thompson.  

Is the May/December relationship between Georgie and Alex believable? Is the ambiguity of their story plausible? Yes. No. Maybe. In a universe of infinite outcomes, everything is possible—perhaps even perfect. That’s the beguiling beauty of “Heisenberg.”
