Posthumous Lemmy solo album due: producer

Motorhead's lead singer Ian "Lemmy" Kilmister, pictured at the Glastonbury Festival in 2015, died in December 2015 at the age of 70 in his adopted home of Los Angeles

A posthumous album is set for release from Lemmy, the gravelly-voiced, hard-living frontman of metal band Motorhead, the producer of the project said.

Jim Voxx, the guitarist of German hard rockers Skew Siskin whose music was championed by Lemmy, said that the Motorhead leader had been working periodically on the solo album since 2003.

"When Lemmy got ill, we stopped working on it, but the recordings were all done," Voxx told online station MetalTalk Radio in an interview aired Wednesday.

Voxx said that the release date was yet to be decided but he expected it to come out "towards the end of this year."

The guitarist said that Lemmy had recorded songs with leading rockers including Dave Grohl of Nirvana and Foo Fighters fame and English punk greats The Damned, although it was not clear which tracks would appear on the album.

The yet-untitled work would be the first solo album for Lemmy, whose real name was Ian Kilmister, although the British singer and bassist had a prolific career with Motorhead and side projects.

Voxx said that the mutton-chopped rocker had worked on the album during breaks from Motorhead's busy touring schedule, sending tracks to Voxx in Berlin for production.

Lemmy, a longtime chain-smoker who boasted of drinking a bottle of Jack Daniel's whiskey every day and of sleeping with more than 1,000 women, died in December 2015 at the age of 70 in his adopted home of Los Angeles.
