My favorite singer in the ENTIRE world is Karen Clark-Sheard. She is one fourth of the premier gospel group The Clark Sisters. Their mother, Dr. Mattie Moss Clark is a legend in the Church of God in Christ, the pentecostal denomination in which I was raised. She is credited as the first composer/director to commit the choir sound onto a record. She is alo the first to seperate the three vocal parts into soprano, alto, and tenor.
Back to the Clark Sisters, Expect Your Miracle is played in my car nearly everyday. Each sister has had much success as individual artists but Karen’s vocal delivery and range has garnered her the position of favorite Clark Sister IMO.
Most of today’s "soulful" singers owe their styles to techniques The Clark Sisters made famous.
