Continuing her efforts toward global expansion, Reba McEntire will headline the massive Barretos Rodeo in Brazil Aug. 19. The event draws more than a million people and has featured American stars Garth Brooks and Alan Jackson. Joining McEntire for the performance will be Jose & Durval, the Brazilian equivalent of Brooks & Dunn. Last year the duo collaborated with McEntire on a cover of Boz Scaggs' "We're All Alone." The song, included on McEntire's album, So Good Together, was a Top 5 hit in Brazil. To prepare for her upcoming concert, McEntire spent the first few days of the month in Sao Paulo making TV appearances. CNT, a major Brazilian TV network, also will air an hour-long special on the singer later this month.
