Valentina and Mr McFall’s Chamber. Valentina takes on the lead part in María de Buenos Aires. This CD was dreamt up by Robert McFall around the time that Revolucionario was recorded. He had asked Valentina back then whether she would be interested in singing the part of María… in the future. And yes, she accepted the invitation and that future is now. This is a major recording of Astor Piazzolla’s masterpiece, his operita, María de Buenos Aires. Valentina, in the lead role, is accompanied by tenor Nicholas Mulroy and singer Juanjo Lopéz Vidal.
