Stacey Kent’s fine new album, “The Changing Lights”, has an unmistakeable flavour of Brazil and bossa nova. It’s not the first time, though, that she’s delved into the Antonio Carlos Jobim songbook: “Les Eaux de Mars”, recorded a couple of years ago, was a clever reworking of one of my favourites, “Águas de Março“.  (Jobim’s gorgeous version with Elis Regina is here.)
