“She was prominent as a jazz singer...” (sidebar: I dunno why they say singer- she can sing- but she is a PIANIST, a brilliant, musical, technical, astounding pianist) “...throughout the 1930s and 1940s. In 1950, she became the first black person to have a TV show, The Hazel Scott Show,[1] featuring a variety of entertainment.” (from Wikipedia)
Look her up on YouTube and prepare to be astounded.
