"Monte Castelo" is a song by Brazilian rock band Legião Urbana, released on As Quatro Estações album.
Written by vocalist and acoustic guitarist Renato Russo, the song brings verses by Portuguese poet Luís de Camões and sections of the Bible.
He struggled to find a melody line and ended up recording many channels with his voice, making the music base and the lyrics so chaotic.
The text became so scary that made guitarist Dado Villa-Lobos and his wife Fernanda fled from the studio after they read the written words.
The situation reached a point to Russo turned off the sound and Bahia threatened to finish the album without him.
