The arrangers for the sessions are Ralph Carmichael, Bill Holman, and Tak Shindo.
[1][2] Jason Ankeny writes in AllMusic, "The Many Moods of Ann Richards captures the singer in a series of different contexts and styles, precisely the kind of project that could amount to little more than a patchwork mess in the hands of a lesser talent.
But arrangers Ralph Carmichael, Bill Holman, and Tak Shindo all prove sympathetic collaborators, spotlighting Richards' smoldering vocals in milieus that perfectly complement her lusty vibrato."
The review praises the blend of Holman's jazz and Shindo's Eastern exotica influences with Richards demonstrating confident versatile performances with both.
She seems to sense the mood of a song well and she good use of an improvisational technique in her phrases.
