He was mine too - This quote below says it all - people who didn't know of him or did but didn't care won't get it, but he was a genius.
From the BBC website - "Lenny Kravitz posted a fulsome tribute on Instagram: "King. Genius. Leader. Teacher. Producer. Arranger. Writer. Multi-instrumentalist. Motivator. Mystic. Through his music and artistic expression, he taught me a lifetime's worth of knowledge. He is at the top of the list of all of the greatest masters. The music he left behind as Earth Wind and Fire, mixed with his messages of love, will live on forever."
