Miami-based Colombian pop idol, Juanes, who organized a star-studded "Peace without Borders" concert in Havana braved death threats from Miami-based critics of the Cuban regime.
What happens when half a million Cubans gather under the broiling sun in Havana's famous Revolution Square?
Typically, over the past 50 years, they'd be subject to a rambling, four-hour lecture from legendary communist leader Fidel Castro.
Despite the strict rule not to bring up politics, Puerto Rican merengue star Olga Tanon, one of 14 artists from six countries performing with Juanes, kicked the show off with the event's central message: "It's time to change."
Easy there, Olga. You know how the Castros feel about that word.
