Michael Ralph Scaccia (June 14, 1965 – December 22, 2012)[1][2] was an American musician, best known as a guitarist for several heavy metal and alternative rock acts, including Rigor Mortis, Ministry and Revolting Cocks.
[3] Scaccia's first band, Spectrum, was formed with high school friends Chuck and Chad Williams on guitar and bass, Johnny Carpenter on drums and Barry (Baron) Lane on vocals.
Scaccia left Spectrum in late June 1982; the next year, he formed Rigor Mortis with schoolmates Harden Harrison and Casey Orr.
In 1989, Scaccia was asked by Al Jourgensen to join his band Ministry for their 1989–1990 The Mind is a Terrible Thing to Taste tour.
He agreed, but left the Ministry again in 2006 before rejoining with Al Jourgensen in the studio to record what would be Relapse, which was scheduled to tour in the summer of 2012.
A memorial service was held for Scaccia on Sunday, December 30 at the Aristide Event and Conference Center in Mansfield, Texas.
