Reviews of the concerts have noted the intimacy between Veloso's and Gil's voices and guitars, with Reuters calling their Montreux performance "pure and poignant," and the Guardian calling it "historic … a classy and emotional performance," saying, "They are now in their early 70s, and they are still remarkable." Their friendship begin in the early 1960s, in Salvador, Bahia, and has endured many triumphs and difficulties over the decades: from their first, historic concerts at the Teatro Vila Velha to performances in music festivals, moves to Rio de Janeiro and São Paulo, incarceration, and exile to London, among many other experiences.
Dois Amigos was produced by Veloso and Gil, with sound engineering by their sons, Moreno Veloso and Bem Gil. The album was released internationally earlier this year.
