An international rocker is creating a rare opportunity to sing about change on the Communist island of Cuba.

Colombian singer Juanes -- a 17-time Latin Grammy winner -- has brought 15 international artists to Havana. He hopes to thaw U.S.-Cuba relations by staging a "Peace without Borders" concert.

But the reaction in Miami, Florida, home to both Juanes and a large Cuban exile community, has not been entirely peaceful.

Juanes has received death threats over the concert via Twitter, he said, and his home in Miami is under police protection.
