Former Red Hot Chilli Peppers guitarist Jack Sherman has died at the age of 64.
The band confirmed news of his death in a post on their official Instagram account on Friday night.
It read: “We of the RHCP family would like to wish Jack Sherman smooth sailing into the worlds beyond, for he has passed.
“He was a unique dude and we thank him for all times good, bad and in between.
“Peace on the boogie platform.”
Jack joined the Chili Peppers in December 1983, replacing original guitarist and founding member, Hillel Slovak.
He played on the band’s self-titled debut album, which was released in 1984, and co-wrote much of their second album Freaky Styley. He also performed with them on their first tour of the US.
Hillel later returned to replace Jack when he left the group in 1984.
He went on to record with artists including Bob Dylan, George Clinton and Bill Madden.
Jack previously spoke of his disappointment at being excluded when the Red Hot Chilli Peppers were inducted into the Rock and Roll Hall of Fame in 2012.
Neither he and former guitarist Dave Navarro were inducted, which the Hall claimed was because only original members, current members and those who played on multiple albums were eligible.
Jack said at the time: “It’s really painful to see all this celebrating going on and be excluded... I’m being dishonoured, and it sucks.”
