The "America's Got Talent" live broadcast of quarterfinal No. 1 kicks off from Radio City Music Hall Tuesday night, Aug. 11, as 12 eager acts compete for America's vote.

It will be the first live show of Season 10 for "America's Got Talent."

Following four rounds of judges' eliminations, 28 contestants remain as the competition for final victory heats up.

Below is a list of the acts and solo artists performing Tuesday night before judges Heidi Klum, Howard Stern, Mel B and Howie Mandel:

Piff the Magic Dragon is the sarcastic magician who dresses in a dragon costume and has a sidekick dog named Mr. Piffles. Guest judge Neil Patrick Harris gave him the golden buzzer. Piff stole a kiss from judge Heidi Klum during the show.

Drew Lynch uses stuttering to his advantage as a stand-up comedian. He began to stutter following an accident in which he was struck in the neck by a softball.

Flexibility, beauty and strength may give Vita Radionova an edge over the other competitors. She is a favorite contestant of judge Howard Stern.

Alondra Santos, who had never sung in front of a crowd until auditioning for the show, sings Mariachi music with a remarkable voice.

Triple Threat is a threesome of geeks with surprisingly beautiful voices. While the judges love their talent, Stern worries they won't get the girl attention needed to succeed as a boy group.

Ventriloquist Paul Zerdin is amusing and very talented. A favorite of all the judges, he has a good chance of winning.

New Bedford's Samantha Johnson has amazing vocals that could land her a win and possibly a future recording contract. She took the AGT stage by storm earlier this summer with a mind-blowing rendition of "(You Make Me Feel Like) A Natural Woman."

Siro-A, a seven member Japanese performance group, uses a mixture of mime, techno music and groundbreaking visual effects to entertain audiences. They have been compared to the Blue Man Group.

The Show Project consist of men with muscular, sexy bodies whose creativity and strength are used to perform acrobatics that amaze.

A Sarasota-based ballroom couple, Craig Smith and Micheline Marmol, specialize in Exhibition Showdance. They have won four world championship titles in dance, so rivals beware.

Singer-songwriter Benton Blount has a country style and fantastic tone that has won over both the judges and fans. His win could land him the Nashville recording contract he's always dreamed of.
