Frevo is a wide range of musical styles originating from Recife, Pernambuco, Brazil, all of which are traditionally associated with Brazilian Carnival. The word frevo is said to come from frever, a misspeaking of the Portuguese word ferver (to boil). It is said that the sound of the frevo will make listeners and dancers to feel as they are boiling on the ground. The word frevo is normally used interchangeably either to mean the frevo music or the frevo dance.

The frevo music came first. By the end of century XIX, bands from the Brazilian Army regiments based in the city of Recife started a tradition of parading during the Carnival. Since the Carnival is originally linked to religion, they played religious procession marches and martial music, as well. A couple of regiments had famous bands which attracted lots of followers and it was just a matter of time to people start to compare one to another and cheer for their favorite bands. The two most famous bands were the Espanha (meaning Spain), whose conductor was of Spanish origin, and the 14, from the 14th regiment. The bands started to compete with each other and also started playing faster and faster, louder and louder.

Caetano Emanuel Viana Teles Veloso (Portuguese pronunciation: [kaeˈtɐ̃nu emanuˈɛw viˈɐ̃nɐ ˈtɛlis veˈlozu]; born August 7, 1942), better known as Caetano Veloso, is a Brazilian composer, singer, guitarist, writer, and political activist. Veloso first became known for his participation in the Brazilian musical movement Tropicalismo, which encompassed theatre, poetry and music in the 1960s, at the beginning of the Brazilian military dictatorship. He has remained a constant creative influence and best-selling performing artist and composer ever since.

Veloso was born in the city of Santo Amaro da Purificação, in Bahia, a state in the northeastern area of Brazil, but moved to Salvador, the state capital, as a college student in the mid-1960s. Soon after the move, Veloso won a music contest and was signed to his first label. He became one of the founders of Tropicalismo with a group of several other musicians and artists—including his sister Maria Bethânia—in the same period. However the Brazilian government at the time viewed Veloso's music and political action as threatening, and he was arrested, along with fellow musician Gilberto Gil, in 1969. The two eventually were exiled from Brazil, and went to London, where they lived for two years. After he moved back to his home country, in 1972, Veloso once again began recording and performing, becoming popular outside of Brazil in the 1980s and 1990s.
