Why They're Hot: The Mexican-born teens turned their hobby into a huge business that's reached a global audience thanks to their signature "tribal guarachero" sound. Despite their success tied to major radio airplay, synch deals (Pepsi) and recently dominating the list of finalists for the upcoming Billboard Mexican Music Awards (Oct. 18 in Los Angeles), Rincón, Presenda and Zavala keep a cool and down-to-earth attitude about their climb in the music business. This past summer they opened up for Justin Bieber in a special concert at the famous Zócalo, the main square in the heart of historic Mexico City in front of about 200,000 music fans. "It was a bit nerve-wrecking," says Rincón, "but once we were out on stage it was an amazing experience that we will never forget."
