Jon Zazula says he knew Metallica would be just as big as Led Zeppelin when he signed them.

The founder of Megaforce Records released his memoir, Heavy Tales: The Metal, The Music, The Madness. As Lived by Jon Zazula, which tells the highs and lows of his career. When he sat down with Loudwire, he revealed how he followed his gut instinct to sign Metallica.

“Well, I thought they would be as big as Led Zeppelin,” he said. “That’s how I measured Metallica. I really [envisioned] them playing the Isle of Wight in England and playing Monsters of Rock and playing arenas in America. Now did I think at that time of them playing stadiums every other day in the United States? No, but I really felt this would be the biggest band in the world from the first note I heard.”
