Louis Johnson, the talented bassist who appeared on the Michael Jackson classics “Billie Jean” and “Don’t Stop ‘Til You Get Enough,” has passed away at the age of 60.

Louis was a founding member of Brothers Johnson along with his brother George. In the 70s the duo worked extensively with producer Quincy Jones as well as Bobby Womack, the Supremes and Billy Preston. They put out several number one hits including “I’ll Be Good To You” and “Stomp!”.

Later, after going solo, Louis, aka “Thunder Thumbs”, played and recorded with a hugely impressive roster of artists including Stevie Wonder, Paul McCartney, Herbie Hancock, George Duke and Bill Withers.

“I’ve never been given parts to play in my whole life. I’m the most rare bass player in the whole world,” Johnson told Rolling Stone in a 2013 interview. “No one ever gave me music paper to read; no one ever gave me anything to read. They tell me, ‘Here’s a track, play what you want.'”

Quincy Jones penned a heartfelt tribute to the late bassist via Facebook:

Louis “Thunderthumbs” Johnson was one of the greatest bass players to ever pick up the instrument. As a member of the Brothers Johnson we shared decades of magical times working together in the studio and touring the world. From my albums “Body Heat” and “Mellow Madness”, to their platinum albums “Look Out for #1,” “Right On Time,” “Blam,” and “Light Up The Night,” which I produced, to Michael’s solo debut “Off the Wall,” I considered Louis a core member of my production team. He was a dear and beloved friend and brother. I will miss “Boot’s” presence and joy of life everyday. ‪#‎RIPLouisJohnson‬
