Spare A Little Rain has more of a jazz feel, the acoustic bass this time teamed with congas, sweetened by electric piano.
With so much music coming from her in a decade of recording, Jackson obviously has lots sounds she wants to explore. Good on her, I say, there's no point sitting on a style or sound if you've got the interest and the goods to mix it up.
