As an American from Tucson, Arizona who loves Brazilian bossa nova from the '60s, may I say these artists definitely have it 'down' with Luiz Bonfa's original composition of Manha de Carnival (Black Orpheus)! What a refreshing interpretation, and I'm amazed with their intonation and sucient observation of Bonfa's concept of his primal tune. This is classical and extremely well done. My many thanks for presenting this on RU-vid!
I think this commenter has a point. This performance is more for a jazz bar setting... Not for a concert. But boring is a bit harsh, as it's just not what you're looking for.
