Paul Raven, bassist behind influential post–punk/industrial outfit Killing Joke has died of an apparent heart attack.

The 46 year–old was the second bassist in Killing Joke and remained with the band until their first break up in 1991. After that, he performed with both Prong and Godflesh and later collaborated with Ministry for their 2006 full length, Rio Grande Blood.

Killing Joke keyboardist Rez Udhin told one media outlet:

Paul was a very amazing man who I loved and trusted very much. He always had great ideas, ventures and always looked out for me as if I were a little brother to him.

"I was very fortunate to be in contact with him several times in his last week and I had great conversations with him, we laughed and joked, which was an integral part of his personality. "Paul will be greatly missed by music fans, friends and mostly his family; his bands will miss him terribly. He was a great man and a unique bass player who has died at such a tragically early age.

Ministry's Al Jourgenson also commented:

I am in total shock. 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.

Our condolences to his friends and family.
