When Barack Obama campaigned for the presidency of the United States in 2008, the topic of race often came up in discussions about him. Obama was born to a black father and a white mother, and questions such as "Is America ready for a black president" and "Is Obama black enough" seemed to follow him on the campaign trail.

Like now-President Obama, Lenny Kravitz is the product of an interracial marriage. In the early stages of his career, record company executives were worried that his music wasn't "white enough" or "black enough" to be accepted by either audience. Since then, the 47-year-old U.S. musician has spent the last 20 years proving that theory wrong by winning fans of all races as well as Grammy Awards and racking up album sales in the millions. It's pretty solid proof that music is color blind.

Kravitz hasn't sung about race for some time, though — not since 2001's "Bank Robber Man," a song about an incident where Miami police detained and handcuffed the singer on the street because he fitted the description of a bank robber. With his latest album, "Black and White America," he has returned to the topic.
