The series places Brazil and the world in the context of 1973 to show how fertile that period was for local music production. Each episode addresses a specific theme—such as military regime censorship, the rise of samba at the time, Brazilian rock, the importance of iconic album covers, production outside the Rio-São Paulo axis, and the renewal of bossa nova. To this end, the series invites musicians like Odair José, Charles Gavin, and Roberto Menescal, as well as journalists such as Silvio Essinger, Paulo Cesar de Araújo, and Renato Terra, to share behind-the-scenes details from that era. Each account is complemented by extensive research, featuring performances and interviews with artists who defined the year and remain fundamental to the history of Brazilian music.
