Paul Raven, best known for his work with post-punk/industrial group Killing Joke and more recently as a member of Ministry, was found dead in a home in Geneva, Switzerland on Saturday.

Initial reports indicate that Raven, 46, suffered a fatal heart attack in his sleep around 6 a.m. He was in Geneva to work with French industrial band Treponem Pal's new album along with singer Marco Neves, drummer Ted Parsons (Prong, Jesu) and members of The Young Gods.

"Words cant describe how I feel right now," wrote Parsons, who discovered Raven's body, on his MySpace page. "I'm devastated. He will be missed by many. He was the king of the one liners."

Raven was born in Wolverhampton, England and joined Killing Joke as a replacement for their original bassist in 1982. He recorded and toured with them during their most commercially successful period, which included the albums Fire Dances (1983), Night Time (1985) and Brighter Than A Thousand Suns (1986).

When Killing Joke disbanded in 1991, Raven and his bandmates (minus singer Jaz Coleman) formed Murder, Inc. with singer Chris Connelly. Over the years he was also a member of Prong, Pigface and Godflesh. Raven also worked as a producer and was at the controls for Toronto band Monster Voodoo Machine's 1994 album, State Voodoo/State Control.

Raven rejoined Killing Joke for their eponymous 2003 album and 2006's Hosannas From The Basements Of Hell. Raven talked to ChartAttack in 2005 about a live DVD called XXV Gathering that Killing Joke released to give fans a taste of their stage show.

Raven began working with Ministry frontman Al Jourgensen in 2005 to record 2006's Rio Grande Blood and this year's The Last Sucker, Ministry's final studio release. Raven was supposed to take part in a worldwide farewell tour next year in support of the album.

"I am in total shock," Jourgensen said in a statement. "The world of music is a sadder, emptier place.

"Not only was Raven an extraordinary talent, but one of my closest, dearest friends. Our condolences and prayers go to his immediate family. He will be truly missed by artists, musicians and his fans the world over."

Raven most recently worked with members of Warrior Soul and The Mission UK on their new collaboration, Mob Research. Their debut LP is in the final mixing and mastering stage and is scheduled for release by 13th Planet Records next year.

A memorial dedicated to Raven has been started on the 13th Planet website.
