Frevo is a dance and musical style originating from Recife, Pernambuco, Brazil, traditionally associated with Brazilian Carnival.

By the end of the 19th century, 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 Catholicism, they played religious procession marches and martial music, as well.

Each dancer worked hard in order to develop a new movement which required much rehearsal, strength, endurance, and flexibility and the fight between the groups moved from the physical to the aesthetical field.

In the 2000s the best-known ambassadors of the frevo is the Recife-based big band SpokFrevo Orquestra, led by sax player Inaldo Cavalcante de Albuquerque, better known as Spok.

These are 17-18 professional musicians - including two virtuoso drummers and a percussionist - who have made it their mission to introduce the world to frevo music.

Adaptation of frevo compositions for smaller formations, commonly without a brass section and made up of Bahian-guitars, drums, bass, electric guitars, keyboards and a singer.

The style developed in the early 1950s in Bahia, spurred by a performance given by the "Clube Carnvalesco Misto Vassourinhas of Olinda" in Salvador (Bahia State) and later by the band Trio Elétrico Armandinho, Dodô & Osmar, gave origin to the trio eléctrico tradition of the Bahian carnival, which fused the frevo with Western pop rock.
