Brazil’s signature dance is the sexy samba, a spicy Afro Brazilian rhythmic explosion that originated on the working class streets of Rio de Janeiro. It’s all samba all the time at Carnival, a gala celebration that has earned Rio a reputation as the world’s best party city. If you miss Carnival, held before Easter every year, not to worry. Rehearsals run throughout the year and you can visit a samba school where preparation and celebration are virtually synonymous. Guide Bernardo Leao has invited the Ulles to experience a samba school.
