Ian Fraser Kilmister, the jagged-voiced heavy-metal singer and bassist known as Lemmy, who led the loud and fast British rock band Motörhead for decades, died on Monday at his home in Los Angeles. He was 70.

Motörhead confirmed his death on its Facebook page. The band said in a statement that Mr. Kilmister, who had dealt with health issues for years, had “a short battle with an extremely aggressive cancer,” which he learned he had on Saturday.

Motörhead had scheduled tour dates across Britain and much of Europe to start 2016. But in an interview with the Swedish newspaper Espressen, the band’s drummer, Mikkey Dee, said the group would not continue.

“Motörhead is over, of course,” he was quoted as saying. “Lemmy was Motörhead. But the band will live on in the memories of many.”
