Mike Pinder, the last original member of the Moody Blues, has died at the age of 82, according to his family.
The keyboardist died on Wednesday in northern California, with the band and bassist John Lodge also confirming the news on Facebook.
'All the love possible goes out from the Lodge family to Mike's family today,' The Moody Blues wrote. 'RIP'
No cause of death has been provided.
It comes after the band's original singer and guitar player Danny Laine died in Naples, Florida, last year.

Laine's widow Elizabeth reached to Pinder's death on Instagram Wednesday.
'Very sad news, the last of the original lineup of the Moody Blues has passed away,' she wrote.
'He is now reunited with Denny, Ray, Graeme and Clint; what a joyous reunion that must be.'
Pinder was one of the Moody Blues' original members, joining Ray Thomas and Laine in 1964 to form the band.
But the Moody Blues struggled to match their initial success, and by 1967 Laine had left, replaced by Justin Hayward.
The Moody Blues then turned to the ambitious, classically influenced sounds of 'Nights in White Satin' and other songs.
