Danny Gokey wowed American Idol judges.

American Idol semifinalist Danny Gokey wowed the judges in his rendition of Mariah Carey’s tune “Hero” at the singing competition’s first performance show of season 8.

The 28-year-old church music director from Milwaukee heaped praises from three of show’s judges.

"You are the hero, man," said Kara DioGuardi. "You give us all hope. You were great."

Gokey was the last to perform in a group of 12 singers out of the top 36 semifinalists. However, it was not a lucky day for contestants Stephen Fowler, Casey Carlson and Stevie Wright as they reaped harsh criticisms from the judges. The top three contestants who will get the most votes will be revealed during Wednesday's live episode.
