Lenny Kravitz pays tribute to Harry Belafonte in this video he created following the news of Belafonte's passing on April 25th. Kravitz handles most of the instruments, including bass, on “How Long Have You Been Blind,” which is a beautiful tribute to his friend. “Rest in power, king,” Kravitz wrote.

American singer-songwriter and actor Lenny Kravitz released his debut album, "Let Love Rule," in 1989 and followed it with such albums as "Mama Said" (1991), "5" (1998), and "Black and White America" (2011).

The song, How Long Have You Been Blind?, was written and originally recorded in 1984 by Floyd Red Crow Westerman, a Dakota Sioux musician and political activist. Belafonte's version never appeared on album or single, only appearing as part of a Canadian television special, Don't Stop the Carnival.
