Because my feelings for Joan Armatrading's work are deeply woven into my personal history, I know the difference between a good and a great Armatrading album. I know that her ballads are best when they retain a sense of the power and intensity that she unleashes on her uptempo songs, which in turn are strengthened by her impeccable sense of delicacy and grace. That's a pretty good description of Armatrading's approach on her latest album, 'This Charming Life.'
