Colombian singer/songwriter Juanes' Peace Without Borders concert, slated for Sept. 20 in Havana's Plaza de la Revolución, has unleashed a maelstrom of debate about the ethics of performing in the country. Juanes will perform with Puerto Rican singer/songwriter Olga Tañón, as well as several other acts from Cuba, Spain and other countries. The free concert will coincide with the United Nations International Day of Peace.

The Peace Without Borders concert is the sequel to a 2008 show Juanes staged on the Columbia-Venezuela border to discourage conflict between the two countries. Like its predecessor, this concert will be free of sponsors, with local production costs covered by the Cuban Institute of Music and Juanes himself. Exclusively for Billboard, Juanes and Tañón explain why they decided to play Cuba.
