Sisters Of Righteous
Sisters Geneva “Gigi” Kinard and Denise Kinard together with cousin Roberta DuBois came from Cincinnati, and they worked with Soul Brother No 1 around the turn of the 70s. Their lovely harmonies can be heard embellishing Brown’s tortured “I Cried”, one of his most compelling ballad performances. And they also appeared behind Vicki Anderson on her King 45 “Wide Awake In A Dream” / “I Want To Be In The Land Of Milk And Honey”.
They also cut four sides under their own names for King which appeared spread over three 45s. Brown produced them all and they were all penned by the Sisters themselves. The tremendous hard driving “That’s How I Feel” is perhaps the best known of their output, but there are others that are equally good. 
Is My Lovin’ Too Slow is a big dramatic ballad full of power and passion. Even better is Hold On To What You Got with its lovely churchy opening from the piano and the beautifully structured vocal arrangement is quite magnificent. Super lead vocal from Roberta as well.
Sadly Roberta has passed on but the Kinard sisters are still in Cincinnati.
