Keni Richards, original drummer for ’80s rockers Autograph, has died at age 60. The cause of death has yet to be revealed.

Founding Autograph guitarist Steve Lynch confirmed the news, alerting fans via social media. “He was the mighty force that was our backbone 1983-1988,” wrote Lynch. “We wish him a pleasant and peaceful journey. Our love and condolences to his family and friends. He will be missed greatly.”

Guns N’ Roses’ bassist Duff McKagan expressed his sorrow as well, tweeting, “Keni will be missed. An amazing soul and funny as hell. Damn. Love you Keni.”

Autograph rose to prominence in the mid ‘80s when their debut album, 1984’s Sign in Please, achieved Top 30 chart status. The album spawned the band’s signature single, “Turn Up the Radio,” but subsequent releases failed to match the debut’s success. Richards left Autograph in 1988, going on to work with another group called Dirty White Boy. Various sources have reported that chronic back issues eventually forced Richards to leave the music business.
