Sílvia is fabulous, and the way she turned her engagement at The Greek into a showcase for other musicians was the height of generosity. Her version of "Mañana" is striking, but the elegiac tone of the words seem better suited to this more subdued version. She is defiant at the prospect of death; these two are contemplative. Your link takes us to an excerpt from a film about Ana Maria Moix; the roundness of the sound makes me think they are miming what they have already recorded. (Still wonderful.) Sílvia sang "Mañana" live recently at an NPR Tiny Desk Concert. I don't think it has hit RU-vid yet, but you can reach it through the NPR home page. Christina Rossetti was the original poet -- for anyone else who cares. AND, playing impeccable rhythm guitar with a little finger-picking thrown in is not that easy. Good listening!
