Sydney Metal band founded by ex-SUICITY guitarist Doug Dalton and former MORTAL SIN drummer Wayne Campbell. GRUNGEON included tracks on the 'Redrum' and 'While My Guitar Gently Kills Your Mother' compilation albums.

Dalton and Sullivan left the fold in 1994 and their positions were filled by guitarist Anthony Hoffman and bassist Dave Collis for a support tour to BRUTAL TRUTH. GRUNGEON broke up shortly after. Campbell rejoined MORTAL SIN in 1996.
