The drummer for British progressive rock band Yes, Alan White, died on Thursday at the age of 72.
This was announced by his family and the band on social media.
Their beloved drummer and "friend of 50 years" died after a short illness at his home near the US city of Seattle, the band wrote on Twitter.
The news shocked and stunned the entire Yes family.
The band now want to dedicate their forthcoming UK tour in June to White, according to the PA news agency.
White was born on June 14, 1949 in Pelton, England.
He joined Yes in 1972 and has been the band's longest-serving member since the death of founding member Chris Squire in June 2015.
He has also worked with stars such as John Lennon, George Harrison and Eric Clapton.
Founded in 1968, Yes was inducted into the Rock & Roll Hall of Fame in 2017.
Their hits include "Owner Of A Lonely Heart", "Roundabout" and "Long Distance Runaround".
White's death caused consternation.
Yoko Ono tweeted that White was a wonderful drummer who was instrumental in the sound of Lennon hits like "Imagine" and "Instant Karma."
"He was always gentle, kind and cheerful."
