An underground revolution is taking place in Cuba. Sentiments once quietly spoken behind closed doors are finding loud expression in a pulsating mix of Afro-Cuban rhythms and rapid-fire speak. Cuban Hip Hop, its dark poetry urging change, despairing at poverty, prostitution, racism and police harassment, is far removed from its counterpart across the Florida straits where misogyny and gangster glorification rules. "It goes beyond mere communication," says Michel Fernández of Hip Hop group Explosion Suprema " it heals the wounds of Cuban reality".
