“Their first record was very different from the record they made after they met me and the guys in Metallica”: Dave Mustaine on the influence he had on the Big Four of thrash metal

Dave Mustaine of Megadeth performs at Canada Life Place on February 28, 2026 in London, Ontario.

Dave Mustaine has divulged that he believes that he’s had a massive influence on his fellow Big Four of thrash metal, namely, Slayer, Metallica, and Anthrax.

In an interview with São Paulo, Brazil's 89 FM A Rádio Rock radio station [via Blabbermouth], Mustaine shares his honest thoughts on the metal community and his overarching legacy.

“I’ve been very invested in the metal community,” he says. “Kerry [King, Slayer guitarist] and I played together [during the early days of both bands], and I showed him how to play Megadeth songs, which was before [Slayer] started having all their pivotal records. Kerry and I had a really great time together.”

As for Metallica, the band he was the lead guitarist for between 1982 and 1983, he asserts, “I wrote music in Metallica, and I wrote music in Megadeth. So I’ve been very influential with the guitar with these three bands.”

He also believes he had an influence on Anthrax’s Scott Ian, stating that the band started crafting a different sound after they met Mustaine-era Metallica.

“When I met Scott and the guys in Anthrax out in New York, same thing happened. Their first record was very different from the record they made after they met me and the guys in Metallica. So I think that's great.”

Ultimately, though, Mustaine is quick to clarify that, “I love all those bands.”

Megadeth recently released their seventeenth and final album, and Mustaine gave Guitar World an exclusive track-by-track rundown of his swan song.
