"Before I Forget" is a song by American metal band Slipknot. Released in June 2005 as the third single from their album Vol. 3: The Subliminal Verses, it won a Grammy Award for the first time in Slipknot history. The song appeared on soundtrack of Guitar Hero III (considered one of hardest songs in the game, mostly because of the extremely quick chord part in the bridge) and MotorStorm.
