Dia Grace

Dia Grace was a singing act from Season 7 of America's Got Talent. She was eliminated in the audition rounds.

Audition
The Seattle Cossacks' audition consisted of performing motorcycle tricks such as holding onto a motorcycle with one hand, and crawling between the two legs of the rider to "Ride of the Valkyries." Howard Stern and Howie Mandel both buzzed the act. Stern and at least one other judge voted "No," eliminating the act from the competition.
