The performers booked their place in the next round on tonight's episode of the NBC competition.
The first 12 acts from this season's Top 48 had performed for the judges and public last night as they vied for the $1 million prize and the chance to headline a show in Las Vegas.
Their success means that Kung Fu Heroes, Airpocalypse, The Hot Shot Tap Dancers, Paul Safy Jr, Nick Pike, Sally Cohn, RNG and Maricar were sent home.
Tonight's instalment also featured a performance from Selena Gomez & The Scene who sang new single 'Round & Round' from upcoming album A Year Without Rain. The cast of Rock Of Ages also performed a medley of songs from the show with surprise guest Dee Snider from Twisted Sister.
America's Got Talent continues next Tuesday at 9/8c on NBC.
