Former Earth, Wind & Fire drummer Fred White has died aged 67.
"Our family mourns the loss of an amazing and talented member," one of his brothers, Verdine White, the soul and funk band's current bassist, wrote on Instagram on Monday
Born in Chicago in 1955, Fred White began playing the drums at a young age.
A few years after his brother Maurice White formed Earth, Wind & Fire in 1969, Fred became their drummer.
Together they won six Grammys.
Earth, Wind & Fire was a huge hit in the '70s and was one of the first to break down the divide between white and black in popular music.
The musical group was popular with both whites, but also had a loyal African-American fan base.
In 1979, they became the first black band to sell out New York's Madison Square Garden.
In Germany, the hits "Boogie Wonderland" and "September" were particularly successful.
The band posted a video of Fred White's death on their Instagram channel showing him performing a drum solo in Essen in 1979.
"Rest in love," wrote the musicians.
Earth, Wind & Fire still gives concerts today.
After his election as the first black US president, Barack Obama invited the musicians to the White House in 2009, which helped the group to regain its popularity.
