I don’t think his credit in Metallica *can be overstated enough*. Plus the songwriting, you know? But you could kind of tell he just had this vibe about him. He had all the latest bands, knew all the latest demos, and with Ron Quintana, they would always hang out, ‘Oh, I got this single that I imported that you don’t have.’ Like ‘Blitzkrieg,’ a lot of the Motörhead stuff, the first Maiden album. Yeah, he guided the ship.”
