Brutal Legend is a metal game. So it's achievements and trophies? Also metal.
Take for instance the game's version of Heavy Metal Flu: Six Degrees of Schafer.
"The "Six Degrees of Schafer" Achievement/Trophy is rewarded when you play with or against Tim Schafer in Brutal Legend's epic multiplayer mode. The achievement is also viral, meaning that once you play Tim (or someone who has played Tim), you then have the achievement, and then when you play someone else, they get it, and then when that person plays someone else, they get it, etc etc, rinse, repeat…. Think of it like the flu, a heavy metal flu if you will… "
Note that the Playstation 3 version has one more trophy than the 360 version has achievements. It's called Rock God, earned for collecting all PS3 trophies.
