'Duo Transcend' presented a truly incendiary acrobatic performance at the 'AGT' semi-finals

Trapeze act "Duo Transcend" returned to the stage to wow both the audience and judges on "America's Got Talent."

The couple took their performance to the next level by combining death-defying trapeze acts with flames and roller skates, much to the delight of the audience.

The duo – a married couple from Salt Lake City, named Mary and Tyce – made a name for themselves during the quarterfinals of the current "America's Got Talent" season.

By the time their set was done, the judges were speechless, and Cowell jokingly thanked them for "nearly giving him a heart attack twice."

Mel B said their performance was nail-biting and flawless, and Duo Transcend was dubbed as the "act of the night."

Their first performance on the show a few weeks ago nearly ended in disaster and involved Mary blindfolding Tyce. Unfortunately, tragedy struck.

The plan was for Mary to fall backward while the blindfolded Tyce catches her, but his grip failed, and Mary fell to the floor.

The camera panned to Mary's mother in the audience, who yelled and covered her head when Mary fell.

One of the judges could be heard asking if "she's okay" just seconds before she stood up, uninjured.

Tyce was clearly shaken, but Mary asked if they could have second chance to do the blindfold trick. The judges said the show is called "American's Got Talent," not "America's Got Perfection," adding that the duo clearly is talented.

Simon Cowell said it "made them human," although he added that their act was slightly more dangerous as a singer's only risk of falling was "falling off key."

The duo thanked their fans after the show, as well as their family who traveled from Utah to be there. Follow their journey by tuning into "AGT" on Tuesdays and Wednesday at 8 p.m. ET on NBC.
