Query: Two masterpieces in one CD

Those two LPs provide a wonderful insight into Nina's musical world: beautiful ballads, thrilling blues, fun rythm & blues and jazz tunes, protest songs, gospels... Nina fills African-American music with countless emotions and with a sincere, truthful vision of life (sometimes very harshly, as in "Four women", an awesome Nina's composition, or in "Let it all out", sometimes with a sweet melancholy, as in "Don't you pay them no mind"). A bittersweet masterpiece that won't only delight your ears, but will also make you think about life.
