Gunmetal Grey was an American thrashcore band that was formed in 2002 as a side project of some San Francisco Bay area hardcore veterans.
Gunmetal Grey's sound was inspired by bands such as Metallica and At the Gates.
This eventually led to the recruitment of both vocalist Eddie Hermida and lead guitarist Brandon Scot into the band.
At that point Gunmetal Grey sought fit to continue the production of their first album titled 'Solitude' only after bassist Andrew Smith was added to the band.
As of 2006, Hernan "Eddie" Hermida departed from Gunmetal Grey to become the lead vocalist for Deathcore band All Shall Perish.
