Mick Fleetwood has led tributes to his “dearest friend” and co-founder of Fleetwood Mac, Peter Green.
Fleetwood said they had “trail blazed one hell of a musical road for so many to enjoy”.
And Stevie Nicks, who joined the band five years after Green quit amid struggles with his mental health, said her biggest regret was not having shared a stage with him.
Green, 73, died peacefully in his sleep,his family said on Saturday.
Fleetwood said: “For me, and every past and present member of Fleetwood Mac, losing Peter Green is monumental.
“No-one has ever stepped into the ranks of Fleetwood Mac without a reverence for Peter Green and his talent, and to the fact that music should shine bright and always be delivered with uncompromising passion.”
The 73-year-old added: “Peter, I will miss you, but rest easy your music lives on. I thank you for asking me to be your drummer all those years ago. We did good, and trail blazed one hell of a musical road for so many to enjoy.
“God speed to you, my dearest friend.”
Blues rock guitarist Green, from Bethnal Green in east London, formed Fleetwood Mac with drummer Fleetwood, bass guitarist John McVie and guitarist Jeremy Spencer in 1967.
He wrote the instantly recognisable instrumental track Albatross, which remains the band’s only number one hit, plus two other early hits, Black Magic Woman and Oh Well. And it was under Green’s direction that they produced their first three albums.
Green left the band after a last performance in 1970 as he struggled with his mental health. He was eventually diagnosed with schizophrenia and spent time in hospital in the mid-70s.
Singer Nicks joined Fleetwood Mac with her then-boyfriend Lindsey Buckingham in 1975 and the band became one of the most successful in the world.
“I am sorry to hear about the passing of Peter Green. My biggest regret is that I never got to share the stage with him. I always hoped in my heart of hearts that that would happen,” she said.
“When I first listened to all the Fleetwood Mac records, I was very taken with his guitar playing. It was one of the reasons I was excited to join the band.
“His legacy will live on forever in the history books of Rock n Roll. It was in the beginning, Peter Green’s Fleetwood Mac and I thank you, Peter Green, for that. You changed our lives.”
