Arguably the best album in a stellar catalog, Previsão do Tempo is a key MPB ("Música Popular Brasilera") record of the seventies. By the time Marcos Valle released this album, he was already ten years deep into his career, having released an impressive bossa nova debut in 1963 (Samba Demais). Valle eventually started to move away from the more pure bossa nova of Samba Demais and Previsão do Tempo is the crown jewel of this departure. As can be heard towards the end of one of Valle's most beautiful songs, "De Repente, Moça Flor", keys often give the album a slightly psychedelic feel. On the catchy "Mentira", his embrace of funky guitar licks and groovy keys yields great results. Emotionally Previsão do Tempo has a nice range, containing playful moments like "Nem Paletó, Nem Gravata" and somber atmospheres like that of "Samba Fatal". Opening with the brilliantly political and melodically strong "Flamengo Até Morrer", Previsão do Tempo is an excellent album from front to back.
