"AA UU" is the fourth single by Titãs, released in 1986. Most of this song consists simply of Sérgio Britto screaming "AA", while the other vocalists reply with "UU". The band Símios made a cover of this song. The song was featured on the Rede Globo telenovela Hiper Tensão[1] and on the soundtrack for the 2008 film Meu Nome Não É Johnny.[2] A song they already played in shows before working on the album, it was the first track to be recorded for Cabeça Dinossauro.[3] The track received some airplay, but not without resistance. It only became a hit after its video was broadcast on Rede Globo's Fantástico.[4]
