NBC's "America's Got Talent" was in Austin, Texas Monday for a round of auditions that included contortionists, a 10-year-old mariachi singer and a human cannonball nicknamed "The Bullet."

Judges Sharon Osbourne, Howie Mandel and Howard Stern once again decided which acts would go home and which would advance to the next round in Las Vegas. Contestants are competing for a $1 millin grand prize and a chance to headline a show in Vegas. Here's a rundown of some of Monday's highlights:

- Young mariachi singer, Sebastian de la Cruz, locally known as "El Charro de Oro," was joined by a backing band as he strode the stage with a voice much bigger than his 10-year-old frame. Sharon enjoyed the performance, and Howie compared him to young opera singer Jackie Evancho, who was AGT's season five runner-up. He got three "yes" votes, and advanced to the Las Vegas rounds of the contest.

- The Acrobatic balancing act, Mik and Ali, is an uncle and nephew team that displays amazing feats of strength and balance. Their performance featured the nephew balancing on top of his uncle, vertically, head to head. Sharon thought they were "fabulous," and Howard said he appreciated the difficulty of the act. Howie loved the edge and danger. They easily advanced to Vegas.

- Timothy Poe is a vet who served in Afghanistan, where he was injured by a bomb while on duty. He suffered a brain injury and now talks with a stutter. He may stutter, but he sings beautifully. He dedicated his performance of the Garth Brooks song "If Tomorrow Never Comes," to his wife, who persuaded him to enter the contest. Timothy received a standing ovation from the audience. Howie said Timothy was a "phenomenal talent." Sharon said the song choice was perfect for Timothy's rich tone.

- Performance artist Joe Costillo creates amazing art by drawing in a tray of sand. He told stories with drawings that were displayed on an overhead screen. He impressed the panel and advanced to the Las Vegas rounds.

- The judges went outside for human cannonball David "The Bullet" Smith, who confessed to being scared every time he performs. He's a father of four who has been doing his act for fifteen years. There were some issues with rain and wind gusts but David eventually got shot out of a cannon and landed safely. He advanced.

Other acts moving on to the Las Vegas rounds include a pair of female contortionists and a young singer and keyboard player named Edan. A plus-size pole dancer and an unintelligible impersonator were among the acts sent home.

NBC's "America's Got Talent" returns on Tuesday at 9:00 p.m. Eastern time.
