NEW YORK (CBS) Musical talent took center stage as results were revealed of the semi-finalists on "America's Got Talent."
Four acts advanced to the semi-finals. Among them were Georgia singer Nathaniel Kenyon, who looked like an "American Idol" hopeful; glow-in-the-dark crowd faves Fighting Gravity; singing sisters Christina and Ali, who are both affected by cystic fibrosis; and Future Funk, picked by two out of three judges.
Selena Gomez and the Scene performed on Wednesday night's episode, as did cast members from the Broadway production "Rock of Ages." Former "American Idol" finalist Constantine Maroulis gave a really memorable vocal performance during the group's rendition of "Don't Stop Believing."
Another 12 acts will perform live in Hollywood, competing for four more spots in the semi-finals, on July 20.
