Jorge Arce and his group, Raiz de Plena, features Comparsa Boricua with Bomba music and dancers, stilt walkers, and masqueraders in parades with a Carnival flavor. Their traditional plena music concerts include percussion, trumpets and trombones, and audience participation in the form of lots of call-and-response chants! Raiz de Plena has made over 1,000 appearances at colleges, conferences, schools, art centers, fairs, and community centers throughout the Northeast, the United States, and Puerto Rico.
