“It was funny when I first met James Hetfield. I was like, ‘Thank you for teaching me how to play guitar. You paved the way for me’”: Mastodon's Bill Kelliher on how meeting his guitar heroes pushed him to improve his craft

The old adage “never meet your heroes” usually rings true. However, for Mastodon's Bill Kelliher, meeting guitar heroes like Metallica's James Hetfield and Slayer's Kerry King were key moments in his career that pushed him to improve his guitar playing. 

“It was funny when I first met Hetfield, who's been an idol of mine. It was in Portugal or some big festival we were doing, and I shook his hand,” Kelliher says on The Rockman Power Hour podcast. “I was like, ‘Thank you for teaching me how to play guitar.’ And he was like, ‘What are you talking about?’ ‘Like, you know what I'm talking about. You paved the way for me.’”

Meeting Metallica’s Kirk Hammett and Robert Trujillo was another surreal moment for Kelliher. “When I met Kirk and Robert, they were walking around together and they saw me, and they came running over and they're like, ‘Hey, man, what's up? Can we get a picture with you?’ I was like, this is a joke. Like, I should get pictures. Yeah, you guys are Metallica. I'm just fucking Bill from Mastodon. That's awesome. It was wild.”

Rubbing shoulders with his heroes was also important for Kelliher to realize that he needed to take his instrument more seriously. One incident, in particular, served as a true wake-up call. 

“Watching Kerry King and Jeff Hanneman warm up before a show and I'm walking around drinking a beer. ‘What are you guys warming up for? Know your fucking songs,’” he recalls. 

“And then I realized there's something to this. I started practicing guitar way, way fucking more. I was like 'You're a guitar player. You're in this really big fucking band. You should be better, like you should spend your time not drinking and playing more guitar. Get better at your craft.’”

Kelliher has previously spoken about his experiences meeting Metallica and their diligent practice routine. In a 2021 interview with Guitar World, he recalled, “Metallica practiced for three hours a night before playing onstage for another two. Meanwhile, we were sitting around drinking beer and picking our noses!”

Mastodon will be heading out on a co-headline tour with Lamb of God this July. The co-headline tour celebrates the 20th anniversary of the two band's 2004 albums Leviathan and Ashes of The Wake respectively. The tour kicks off on July 19 at Grand Prairie, Texas, with Kerry King supporting on select shows.
