Mike Scaccia, the guitarist for Ministry and Rigor Mortis, died December 22 while onstage with Rigor Mortis at a club in Ft. Worth, Texas. He was 47. Scaccia reportedly asked the club to turn the strobe lights off before he collapsed from an apparent seizure. He was pronounced dead at the hospital.

Scaccia was a member of several bands, including the Revolting Cocks, Lard, and Buck Satan, but he is best remembered for his work with Ministry. In 1989, six years after forming Rigor Mortis, Scaccia joined Ministry and appeared on the group’s most commercially successful release, 1992’s Psalm 69: The Way to Succeed and the Way to Suck Eggs. In 2003, Scaccia reunited with Rigor Mortis, and more recently, he contributed to Ministry’s latest album, Relapse.
