José Afonso or Zeca Afonso became an icon among Portuguese left-wing activists due to the role of his music in the resistance against the dictatorial regime of Oliveira Salazar, resistance that triumphed in 1974 with the pro-democratic leftist military coup of the Carnation Revolution. His song Grandola, Vila Morena is closely associated with the revolution, since it was chosen to be the password transmitted by radio for the beginning of the movement that toppled the dictatorship.
In the ensuing revolutionary process, Zeca was a very active musician and continued composing political and folk songs, often criticizing the post-revolutionary changes. Years after his death, Zeca Afonso is still widely listened to, not only in Portugal, but also abroad.
The concert was sponsored by the Portuguese embassy.
