Brazil has the most diverse music culture: Under the umbrella of música brasileira one finds a wide array of ethnic influences (African, Portuguese, Amerindian, Latin, North American); practically every musical genre (jazz, folk, pop, reggae, hip-hop, rock, electronica); and styles born in Brazil (samba, bossa nova, lambada, axé, baião). It takes an expert to keep it all straight and make it accessible to the novice listener. Enter Gene de Souza, who manages to tread his way through the waters of Brazilian music with style and ease. Every Sunday from 6:00 p.m. to 7:00 p.m. he brings listeners a variety hour with bossa, samba, jazz, pop, and more, followed by a special one-hour segment with a different theme each week. So get out of your box and embrace o espírito da música brasileira. It'll open up a new world.
