Marshall is best known as a member of the Sydney metal band Dungeon with whom he recorded three albums and toured extensively throughout Australia, Europe and Japan between 2001 and 2005.
While most of the group's album A Rise to Power had been recorded by the time he joined, several tracks feature Marshall's solos.
He also played on the studio albums One Step Beyond and Resurrection and on the live DVD Under the Rising Sun that was made during the band's 2003 tour of Japan.
In late 2005 Marshall founded Paindivision, originally with Dungeon's Tim Yatras on drums but before this band's first live performance the name was changed to 20 Grams.
[5][6][7][8][9][10] The album features some of the world's best known heavy metal singers, including Zak Stevens, Mike Vescera and Steve Grimmett.
