Lenny Kravitz has not been silent about his racial background. He has been known to tell his story through music. In his recent album, Black and White America, he discusses the world in which his parents met and he was raised.
In this video he shares what it was like being called out by a student on his first day of school that his father was White and what it was like being a mixed in school.
