Even as a toddler, Ailton Nunes was drawn to the joyful, energizing sounds of samba music, with its clinks, bongs, and bangs filling the air. It was part of his heritage and practically the heartbeat of his Mangueira neighborhood in Rio de Janeiro, Brazil. But samba was more than music; it was a way to connect with the past and dream of the future. And samba united not only Ailton's neighborhood--it united all of Brazil, especially at the annual Carnaval festival with its samba parades and competition.
