Gal and Caetano are a great duo. I am not as knowledgable as one of the other reviewers, but there is obviously a great chemistry between the two. This is a relaxing disc-- even the fast songs are gently tropical. I'm a big fan of Caetano Veloso's songs, and they comprise two-thirds of the disc. Gal Costa has the right sound for these songs, too. Her voice seems to float on top of the music. The liquid purity of their voices matches beautifully, as well as the easy flexibility of their rhythm. They each sing some on their own, and a couple together, notably Coração vagabundo. Others songs than particularly stand out for me are Domingo, Nenhuma dor, Remelexo, Minha senhora , Quem me dera and Maria Joana. Text of the songs only in Portuguese, but the English notes translate three of them.
