Rolling Stone reports that Mike Scaccia, guitarist for metal bands Ministry and Rigor Mortis, has died. He collapsed on stage with a seizure last night in Fort Worth, Texas after asking the club to turn off the strobe lights. He was 47.

Scaccia formed Rigor Mortis in 1983. (The Fort Worth show was a 50th birthday celebration of that band's singer, Bruce Corbitt.) Then, in 1989, Al Jourgensen invited Scaccia to join Ministry. His first recording with the band was their acclaimed 1992 album, Psalm 69: The Way to Succeed and the Way to Suck Eggs. He was a part of the band on and off over the years. He was most recently featured on their 2012 album, Relapse.

Here's a statement from Jourgensen:

"I just lost my lil' brother and my best friend – the 13th Planet compound is devastated, completely in shock and shattered. Mikey was not only the best guitar player in the history of music, but he was a close, close, close part of our family – and I just lost a huge chunk of my heart today. Our lives are forever changed. Life without Mikey is like orange juice without pulp – kind of bland. I have no words to express what this guy meant to me, my family, my career. . . . everything! ... Rest in peace my brother, my friend, my heart. Please pray for Mike Scaccia and Jenny, his wife and their children, and his family."

Here's a statement from Corbitt (via Rolling Stone):

"My brother is gone! The only reason I am who I am is because of this man. If it wasn't for him I wouldn't even be in a band. RIP Mike Scaccia! The greatest guitar player I ever knew!"
