MPB (música popular brasileira) is an acronym for Brazilian popular music.
The term emerged in the late 1960s, coming from a generation influenced by the bossa nova style, but intended to achieve new artistic projections. In a way, it broke with the bossa-nova musical making, at the same time that it embraced him.
The MPB corresponds to a generation that emerged around the era of Brazilian TV Festivals – TV Record, TV Cultura and TV Tupi. This generation had new composers and interpreters, who suggested embracing Brazil as a whole.
