The tragic news was confirmed by members of the legendary band.
Dave Davies of the band shared a throwback photo of the band alongside the caption: “Totally devastated by the sudden loss Kinks keyboardist Ian Gibbons.
Sharing the same photo on Instagram, Dave wrote: “Ray called me this morning to break the news.”
He passed away at his home on Thursday.
“To simply say Ian will be missed would be an understatement”
Sir Ray Davies
Ian was part of the band between 1979 and 1996.
The band’s frontman Sir Ray Davies said: “To simply say Ian will be missed would be an understatement.
“My first thoughts are for his family and loved ones.”
The band’s drummer Mick Avory said: “I’ve known and worked with Ian for 40 years and I shall always remember him as a good friend and great musician.
“I will miss him so much, especially as we were still working together.
“It’s so sad he had to go so quickly before anyone could say goodbye.”
Ian’s cause of death is currently not yet known.
The Kinks are known for iconic songs such as You Really Got Me, which is still easily recognisable today.
Ian was late to the band’s line-up after The Kinks in 1964.
Last summer, in June 2018, the Davies brothers announced they would be making a new album along with Mick Avory.
They were inspired to get back together after a recent tour from The Rolling Stones.
The Kinks split up in 1996 due to tension between the Davies brothers and commercial failure from their last few albums.
