Portuguese fado singer Carlos do Carmo specialised in songs about his beloved Lisbon, such as poet Ary dos Santos’ jaunty “Lisboa Cidade Abril” (Lisbon in April). But his roots went deeper, as in “Desgarrada” (Torn), a rare duet with his mother, Lucília do Carmo. And his distinctive clear tenor voice cuts like a cool breeze through the piano-accompanied “Rosinha” with Brigada Victor Jara.
