Rock entered the Brazilian scene in 1956, with the release of a Portuguese version of Bill Haley's "Rock Around the Clock".

Rock (earlier called rock and roll--also spelled rock 'n' roll) is a form of popular music, featuring vocals (often with harmony), electric guitars, and a strong back beat; other instruments, such as the saxophone, are common in some styles. Rock, born in the United States, has become popular across the globe, and has evolved into a multitude of highly-varying styles. The genre of rock is broad, and its boundaries loosely-defined. It is sometimes used to describe a number of genres only distantly related, including soul and heavy metal.
