Too bad, few Americans even noticed. A superstar in her native Brazil, where she can pack a 70,000-capacity soccer stadium and commands crowds of millions during Carnaval, Sangalo kept the almost-entirely-Brazilian audience on its feet over the course of three hours and five costume changes.

Dancing frenetically, the crowd of 14,500 sang along with every word of her samba-inflected dance pop songs like "Festa" (Party) and "Acelere" (Accelerate).

"I just want you to be proud of me, and I want you to be proud of the show I brought here," Sangalo said from the top of a massive, thrusting stage pulsing with lights and video — designed by the man responsible for this year's Super Bowl halftime show, Bruce Rodgers.

In Brazil, Sangalo's show was touted as her first step toward conquering the US, placing her in a pantheon with the likes of Madonna, the Rolling Stones, Beyonce and U2.
