Spawning from Brazilian psychedelia and Anglo-American hard rock, Módulo 1000 represented a fusion of both sonorities, coming up with something new in the Brazilian musical scene. The Rio de Janeiro group, featuring Luiz Paulo Simas (keyboards and vocals, later with Vimana and O Terço), Eduardo Leal (bass guitar), Daniel Cardona Romani (guitar and vocals) and Candinho (drums, later with VIMANA), would put out only one album, 1971's "Não Fale Com Paredes", a clear display of their musical influences, ranging from Black Sabbath and Quatermass to Os Mutantes through early Pink Floyd. The nine pieces that made the album display an array of guitar-heavy and keyboard-drenched music, featuring multiple vocals singing protest lyrics - probably one of the reasons why the album was ill-received by the media. The album has achieved a collectable value today, especially in Brazil and Europe, where it reached cult status. A CD re-edition of "Não Fale Com Paredes" saw the light of day in 1998. An early example of Brazilian progressive rock, Módulo 1000 are an essential listen to anyone wishing to gather more knowledge about this musical scene.
