Obviously this is a situation of "different strokes for different folks" ... Ms. Ferrell has garnered accolades from the jazz world, but her vocal style is not to my taste ... I have a problem with vocalists - and even instrumentalists who try to put every note of the scale into every musical phrase ... and as for facial expressions or other 'gyrations', they also bother me ... I always found it difficult to watch Jim Nabors and Celine Dion (in fact, I don't even like her singing) ...
But, like everything in the world, it's all a matter of PERSONAL preference ...
