Cirque Du Soleil “Crystal” is spectacular beyond belief.

“Crystal,” through Feb. 2, PPL Center, Allentown, transports you to a symbolic world of sight and sound with astounding performances by skilled artists who seem to defy gravity as they zoom through the air into each other’s arms, suspended from ropes, and leaping from and over steep ramps.

Cirque Du Soleil’s “Crystal” is enthralling, thrilling and inspiring. You marvel at the athleticism of the performers. Each creates a character, enhanced by brilliant costumes and daring choreography.

That most of the entertainers are performing on skates on ice gives, if you will, an edginess to the show that is captivating. You cannot look away. You will look on with jaw-dropping, eye-popping excitement.

It’s theater as pantomime. It’s kinetic living sculpture. Though each move is dramatic, each motion is gentle. Strength through tenderness. It’s a psychological thriller. It’s an ice opera. It’s all this and more.

The Jan. 30 performance was seen for this review.

The show starts surreptitiously enough with three musicians, an accordionist, a violinist and a triangle player, strolling along the perimeter of the arena ice. Nate Cooper, an Easton High School graduate, appears, tossing actual snowballs to the audience and then raising a bullseye target, inviting the audience to throw back the snowballs, which they do to everyone’s delight. Cooper provides comedic relief throughout, including pedaling perhaps the world’s first Zamboni.

After the show’s introduction announcement, the voice of a young girl is heard. This is the voice of Crystal, the show’s title character who explores her imagination, against a mountainous backdrop that changes hues from silver to blue and more, as she takes the audience with her.

Through the use of incredible lighting, projections and sound, Crystal skates on thin ice and seems to plunge through the ice. She reexamines her upbringing in a family content to sit at home in front of the living room television screen.

Crystal sees Reflection, a nearly-identical character, her alter-ego, as she gets in touch with her inner self and is handed a pen to write her own story and express her world view, which suddenly includes a juggler, who tosses five or more balls so fast that they are a blur.

Crystal then swings high above the ice as her Reflection skates below. Next, a hockey game on a frozen playground takes on the appearance of a pinball machine as dramatic red and yellow lighting suffuses the ice. The hockey players use large chutes to launch themselves into the air as they do flips and somersaults.

After intermission, Crystal is caught up in a maze of transparent panels symbolizing a big city. Skaters zoom past at astonishing speed. She witnesses, as does the audience, pendular poles, which as the name implies, move like pendulums while acrobats swing on them and even jump from one pole to the other.

Microphones affixed to ice skates amplify a tap dance on ice. A chair balancing act builds with some six chairs, one on top of the other and a man balancing upside down on his hands at the top.

There is a romantic waltz-style dance on the ice. Crystal is lifted high above by her partner on aerial straps. The orchestral music swells. Talk about getting swept off your feet.

Crystal’s Reflection appears, this time in the form of three figure skaters. The Shadow characters return, bringing Crystal back to reality. Of course, with Cirque Du Soleil, it’s a reality like no other.

“Crystal” has figure ice skaters, extreme ice skaters and freestyle ice skaters, as well as acrobats, musicians and a comic character (Cooper). Eighteen different nationalities are represented in the cast.

The ice skating is often synchronized and includes incredible lifts and maneuvers. The figure skating is Olympic-caliber. “Crystal” is a terrific event for couples and for parents and guardians and children, as well as for grandparents and grandchildren.

If you haven’t seen Cirque Du Soleil “Crystal,” it’s a must-see. if you’ve been it before, “Crystal” is worth seeing again ... and again.
