Inaldo Cavalcante de Albuquerque, better known as Spok, is a Brazilian musician who is one of the main frevo composers in the state of Pernambuco. His big band, composed of 18 musicians is considered one of the most important frevo groups in the city of Recife. It has performed in many countries of the world, spreading the frevo style of rhythm.  

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.
