When João released “Quem é Quem” in 1973, he had already been in the music industry for over 20 years, gaining national and international recognition. Nevertheless, the album marked the beginning of a new phase in his career: the surprising multi-instrumentalist included lyrics in his songs for the first time. It is one of his most important albums, which now returns to shelves on 180-gram vinyl as part of the “Classics on Vinyl” collection from Polysom.

The album was produced by Milton Miranda and Marcos Valle, with arrangements by João Donato, Maestro Gaya, Lan Guest, Laércio de Freitas, and Dory Caymmi. It features 12 tracks, the vast majority of which are authored by him, with collaborators such as Geraldo Carneiro, Lysias Ênio, Paulo Cesar Pinheiro, Caetano Veloso, and João Carlos Pádua. The only exception is the song “Cala Boca Menino” by Dorival Caymmi.
