Ray Charles Robinson Sr.- was an American singer, songwriter, and pianist. He is regarded as one of the most iconic and influential singers in history, and was often referred to by contemporaries as "The Genius". Among friends and fellow musicians he preferred being called "Brother Ray". Charles was blinded during childhood, possibly due to glaucoma.
Charles pioneered the soul music genre during the 1950s by combining blues, jazz, rhythm and blues, and gospel styles into the music he recorded for Atlantic Records. He contributed to the integration of country music, rhythm and blues, and pop music during the 1960s with his crossover success on ABC Records, notably with his two Modern Sounds albums. While he was with ABC, Charles became one of the first black musicians to be granted artistic control by a mainstream record company.

Nina Simone - was an American singer, songwriter, pianist, and civil rights activist. Her music spanned styles including classical, folk, gospel, blues, jazz, R&B, and pop.
The sixth of eight children born from a poor family in Tryon, North Carolina, Simone initially aspired to be a concert pianist. With the help of a few supporters in her hometown, she enrolled in the Juilliard School of Music in New York City. She then applied for a scholarship to study at the Curtis Institute of Music in Philadelphia, where, despite a well received audition, she was denied admission,[4] which she attributed to racism. In 2003, just days before her death, the Institute awarded her an honorary degree.
