A leading luminary of Brazilian pop, Gilberto Gil turns his live shows into a high-wire act, boldly melding rock and funk with the rhythms of his home country. An electric guitar snakes its way through the nimble rhythms of “Dia de Festa,” while the samba of “Aquele Abraço” bursts into a boisterous street party and an 11-minute version of “Batmakumba / Exaltação À Mangueira” builds from a slow hush into a furious fusion jam.
