Returning in The Coup De Grace
Right after leaving Danzig, Chaussee rejoined his second band The Coupe De Grace and participated in recording of a demo and touring the Midwestern United Statesin 1999.
After the unsuccessful audition in Killswitch, he joined Stereomud in the summer of 2000, but met with similar results. "After rehearsing for a few days we recorded our first demo in Atlanta and all agreed we had something special going on. The band was formed, almost... Once we had about 10 songs, the band decided that we could use another guitarist to augment the sound. I called up my friend Mark Chaussee who came in and played with us for about two months. Things didn't work out with Mark and we tried out a bunch of other guys." – Erik Rogers, PRP.
Jimmy Coup
In 2003, Chaussee returned with James Mecherle, now known as Jimmy Coup, to work on a "full-on metal" album with ex-The Coup De Grace guitarist Steve Wresh and drummer Brett Degendorfer. "It's gonna have lots and lots of guitars, killing double leads, tough vocals and hit hard. All the shit I love!" – Jimmy Coup, Unearthed Archives.
Marilyn Manson
Chaussee joined Marilyn Manson in autumn 2004 replacing the recently departed John 5, as a temporary live guitarist for the Against All Gods world tour in support of Marilyn Manson's greatest hits collection , where tours proceeded from October, 27th, 2004 till August, 31, 2005. Chaussee's style of play featured an original and exotic heavy sound, similar to "old-school" heavy metal – crude and unpolished, contrasting the glam-rock influences of former guitarist John 5 and the former style of the band as a whole. Mark lent a more rigid, gloomy and aggressive sound to the band. "I thought Mark added something great and different to the tour. We haven’t had the opportunity to write songs together" – Marilyn Manson.
