A four-time Grammy winner for best male rock vocal performance, Lenny Kravitz now sets his sights on a Best Song Oscar nomination for his work on the biopic “Rustin.”

“The first thing that touched me about this wonderful film was how little I knew about Bayard Rustin – and I grew up in a family that taught me so much about civil rights,” Kravitz, 59, began in a Zoom press conference Monday.

His father was Jewish NBC-TV producer Sy Kravitz, his mother the Black actress-activist Roxie Roker, who starred as half of TV’s first interracial couple in the long-running sitcom “The Jeffersons.”

Rustin, portrayed by the out actor Colman Domingo in what’s predicted as an Oscar-nominated performance, was influential in befriending and strategizing with Martin Luther King. He was the architect of the historic 1965 March on Washington where King gave his “I have a dream” speech.  Because Rustin was gay, he was discriminated against and virtually erased from history.

George C. Wolfe’s film aims to resurrect Rustin in popular consciousness.

“Here is the person behind the march on Washington and I wanted him,” Kravitz said, “to get his due and for us to feel what this man accomplished.”

So Kravitz went to Wolfe about doing the song that became “Road to Freedom.”

How does he start, get inspired?

“I got quiet and I waited for what the creative spirit was going to begin. I sat down at the piano and waited for the first chord. And I ended with ‘Road to Freedom.’

“Even though I wrote the song, I had many conversations with George about it.  It’s his film and the story he’s telling, so everything I wrote had to fit him.

“The song comes on at the end of the film when the credits are going down. I’ve done music for movies but never written something specifically as a theme for a movie, so that was exciting for me.

“Each line starts by saying something: We are here to make the dream come true. The dream is not that time but every day we live. The lyrics are about moving forward, faith and walking that journey until we reach that goal. We’re on the road to freedom. This road is long, the road is hard and this moves from generation to generation.

“The collaboration was interesting. A lot of time when they use your music for films, it’s a vibe. This was very specific. I ran each word, consonant and vowel by George. This went on for like three weeks, ‘bro. It really had to be specific and simple. And to the point.

“It was a challenge but a wonderful challenge.”
