O Trem Azul is a Brazilian song written by Lô Borges (music) and Ronaldo Bastos (lyrics), first released in 1972 on the Clube da Esquina album through Odeon, with Milton Nascimento among the key collaborators. It is a milestone of the Movimento Mineiro and the Minas Gerais scene, admired for its rich chromatic harmonies and unconventional, expansive chord progressions that blend MPB with psychedelic influences. The lyrics speak of things left unsaid and phrases the wind keeps reminding us of, using the blue train as a metaphor for life’s journey and the sun on the head. Elis Regina also recorded a famous live version on an album titled O Trem Azul, captured from one of her late performances. The song remains a landmark of Brazilian music and a defining piece of the Clube da Esquina movement.
