Input: Over the years I've bought several Dionne Warwick albums that I've listened to with great enjoyment. I find this particular excursion, however, a sad disappointment. It just doesn't work. The instrumentals almost seem like parodies of Vegas back-up arrangements. Miss Warwick sounds as if she is out of her element. And the sound quality is mediocre. Ms. Warwick is a singer that I respect and admire. But this particular album does little to burnish her legacy.
Output:
Negative
