"[1] The New York Times highly praised all the technical aspects and costumes, but felt that it did not succeed in a particularly compelling story; rather it was "essentially about the kind of wild physical feats that all Cirque shows are about, their jaw-dropping effect multiplied by the huge dimensions of the theatrical space.

In one scene, the entire deck is covered with 350 cubic feet (9.9 m3) of imported granular cork from Portugal which creates the realistic appearance of a beach.

It weighs 75,000 pounds (34,000 kg), and slides in and out like a drawer to provide a horizontal stage and carry massive set pieces such as the Wheel of Death.

In 2008, the unique floating stages earned Kà the prestigious Thea Award for Outstanding Technical Achievement from the Themed Entertainment Association.

The Kà theater, which has a capacity of 1950 people, is equipped with a total of 4774 loudspeaker drivers in 2139 cabinets: a pair of speakers at ear level in every seat and hundreds more strategically placed around the auditorium.

[9] The multimedia projection in the show utilizes both infrared video motion detecting as well as a system of touch-sensitive panels beneath the surface of the main 'Sand Cliff' deck.

A similar example of the infrared portion of this technology can be seen in some movie theater lobbies where people can step on and burst video projected bubbles.

If a harness or wire were to fail, a fail-safe mechanism is in place which would lower the performer to the stage or in the aisles to safely detach from the cabling system.

[12] On June 29, 2013, cast member Sarah "Sasoun" Guyard-Guillot, an acrobat from Paris, France, died after she fell about 94 feet from the show's stage at MGM Grand.

[14] It was the second time in less than a week that a Cirque show on the Strip was halted for an accident involving one of its artists; a performer in one of the final preview performances of Michael Jackson One at Mandalay Bay suffered a mild concussion after slipping through the slack rope in the show's “Stranger in Moscow” scene, missing the protective pad below the act and landing hard upon the stage.

[16][17] The choreography incorporates several types of acrobatics and martial arts, including fight scenes using modern wushu taolu, Chinese opera, Poi for manipulating staves and batons, Brazilian Capoeira dance, bungees, aerial straps, swing poles, and a wheel of death.

Twenty minutes before curtain, two musicians enter the lobby and climb up to two stringed instruments specially designed for Kà and integrated into the architecture.

Ten minutes before the show, actors appear in the metal framework to the left and right of the stage and perform flips and leaps assisted with ropes to dive into the audience and attempt to scare viewers.

[37] Cirque du Soleil utilized a new type of digital screen printing in order to design many costumes for Kà, examples of which can be seen in the Forest People, Archers, and the Counselor's Son.

"[38] The album features the voices of Élise Velle (René Dupéré's wife), Ella Louise Allaire (vocalist, arranger and vocal coach) and a young soprano boy named Philippe Lapan-Vandal.

In addition, the 'inspired by' tracks, with the exception of "If I Could Reach Your Heart" (performed by Élise Velle), feature the voice of Canadian world artist Nitza Melas.

Through the music of Kà, René Dupéré attempts to provoke various emotions and moods such as drama, emergency, serenity, passion, and even "the birth of love".

[39] Songs in the show that are not on the soundtrack album: Cirque du Soleil and Marvel Entertainment teamed up to adapt Kà through a limited four-part series of collectible comic books.

Glass, artist Wellinton Alves and colorist Jean-Francois Beaulieu, these comics follow the heroic journey of the Imperial Twins, separated by war, who encounter adventure and peril at every turn on their quest to reunite their kingdom.

The first installment debuted at the Marvel booth at the 2012 San Diego Comic-Con on July 12 – 15, then a wide release followed into comic book stores and a digital download version with subsequent issues to come.
