The classic jazz vibe and very melodic Zee Avi. Her single "Bitter Heart" A perfect sound for a walk in the park, a sunny morning full of flowers and birds singing while feeling dancy and all smile though the lyrics are far from being sunny. She admits most of her piece are from personal experiences, the dark, bittersweet qualities of romance with a crack left open for hope and optimism. I would love to see her play live someday.
