"Our mission is to get some edgy music in front of our family," says Hetfield in an new interview with WRIF host Meltdown. "After 30 years, Metallica's got a dedicated and beautiful bunch of folks that follow us around. A lot of young metal bands, young alt bands, young �whatever�rock kinda bands�we wanna get them up in front of people. This is what we're trying do is help spread the word of kinda edgy music. Lots of different stuff represented here on the lineup."
