14 Bis is a Brazilian pop-rock band. The band took its name from Santos-Dumont's 14 Bis airplane. 　　The band was formed in 1979 in the state of Minas Gerais, when the members of two bands, O Terço and "Bendegó" decided to merge. Flávio Venturini and Vermelho, two founding members of 14 Bis, were also members of the Clube da Esquina band. 　　Música popular brasileira is a strong element in many of 14 Bis compositions. The influence of progressive rock and caipira (hillbilly) is evident in many of its compositions, such as in their use of analog keyboards and complex vocal arrangements.
