ex-Killwhitneydead/The Demonstration guitarist Charles Matheny has passed away at the age of 31. Former bandmates Killwitneydead comment: Killwhitneydead commented: “Just found out some really shitty news. One time guitarist for KWD and The Demonstration, Charles Matheny, has passed away.

I hadn’t seen him in several years, but we definitely had some fun times on that first KWD tour in 2006. A good guy is gone far too soon.”
