ENTERTAINMENT: Vegas has four out of 40

  Las Vegas continues to hold a major presence on “America’s Got Talent,” with four local acts among the 40 who made the cut on the NBC hit talent show. They move from taped preliminaries to live competition (from Los Angeles) starting Tuesday.
  The local contestants:
  — Alizma, three Polish musical sisters who have been shopped on the Strip for years by local producer Blair Farrington.
  — Sabrina “Bri” Bernstein, a local teen who in 2006 was named one of five finalists for the “Sparkle in the Spotlight” music contest sponsored by CoverGirl. Bri was selected as a finalist out of 250,000 entries.
  — Mario and Jenny (Ferreira), a variety and acrobatic act. Mario’s brother Tino has long worked in shows such as “V — The Ultimate Variety Show.”
  — Mosaic, the a capella group often featured in comedian George Wallace’s show at the Flamingo.
  The big surprise was the fact that Flamingo magician Nathan Burton didn’t make the cut. “It was my greatest vanishing act ever,” says Burton, who had entered again because his career got such a boost from his sequence of appearances on the show’s first season.
  Producers initially didn’t object to Burton competing again, but changed their mind after seeing his building wrap on the side of the Flamingo while filming a segment featuring Donny Osmond with British amateur singing sensation Susan Boyle. It didn't help to tell them he had to pay for the wrap himself.
  “They’re already getting heat for how many pros are on the show,” Burton says.
