It is not too surprising that Shaw found her greatest successes in pop/soul music for the stylized way that she bends nearly every note and overplays the lyrics (not much subtlety here) fits that idiom quite well. She does her best on Annie Ross's "Twisted" but sounds much more comfortable shouting out over r&b vamps, making this recording of limited interest from the jazz standpoint.
