20 FEET FROM STARDOM

Very well done documentary featuring the usually un-credited, seemingly  anonymous  singers who create with their marvelous voices the rich accompaniment that enhances the performances of the lead singers.  Personally I'm not a fan of this particular type of music, which consists of powerfully belting out the syllables.  They do know how to make the most of harmonies --- unfortunately, I'm about 20 years  too old to enjoy this era.
