I absolutely adore Sara Serpa. She has made two records with Ran Blake that rival (IMO) his work with Jeanne Lee, though the two are very different. Both albums are equally sublime-- Camera Obscura (Inner Circle, 2010) & Aurora (Clean Feed, 2012). Her own quintet, with which she works in vocalese, is a thing of beauty. Mobile (Inner Circle, 2012) is the latest and best. I can't wait for her next release.
Here is her take on "When Sunny Gets Blue" with Ran, which was performed by Lee on Newest Sound Around in 1962.
