RIO DE JANEIRO — If you think Brazil is just about bikinis and bossa nova, think again.Terrestrial network TV Globo will broadcast the National Bull Rodeo Circuit finals and coverage of the 48th Barretos Fest, the largest rodeo and country music event in Latin America. The annual cowboy extravaganza unfolds Aug. 21-31 in Barretos, a small town in Sao Paulo state. “Barretos is the second largest rodeo in the world, behind the Las Vegas event,” says a fest spokeswoman. “It is not just a sports event. It is a lifestyle that is growing in Brazil.” Organizer, the Independentes Club, expects 800,000 will come to see it. The fest also includes concerts by performers including local country music stars Zeze di Camargo and Luciano and Vanessa Camargo, nightclubs, kiddie attractions and a trade show. Earlier this year, Globo consolidated its hold on the event by inking a four-year, exclusive TV rights accord with the Independentes. Globo lost TV rights in 2001 to rival network SBT.
