They released their first, self-titled, album in December 2013, with tracks about Maria I of Portugal, Guaraní War, Fernão Dias' expeditions and legends Matinta Perera and Iara. All tracks are sung in English except for "Paiol em Chamas", about explosions in weapons depots of the Brazilian Army in 1958, an event involving a military who was Guimarães' grandfather. The title track also contains part of its lyrics in Portuguese and talks about the Revolta da Armada, which names the quintet. In this song, voice actor Sílvio Navas, famous for his work in "ThunderCats"'s Mumm-Ra, lend his voice to the parts spoken by marshall Floriano Peixoto.
