Believe it or not, before Metallica were the biggest band in the world, they were trying to get their name out there just like any other band in their garage days (rimshot).
Former bassist Ron McGovney tweeted out a photo of the band's first business card and wrote "Original Metallica business card. The phone number was the one I had in my bedroom in 1979. I moved to our rental house two doors down in 1981 and took the number with me. That house was where Metallica started. I lived in a condo 1983-1987 and had that same number."
Blabbermouth reports that McGovney previously told Shockwaves radio that he made the card "to send to the club promoters along with our demo. The card was supposed to just have the Metallica logo and a contact number," he explained. "But I thought it looked too plain and decided it should say something under the logo. I didn't want to put 'hard rock' or 'heavy metal,' so I coined the term power metal. I thought it had a nice ring to it. No band had used that term before as far as I knew. I remember bringing the business cards to the band, and Lars got so pissed off at me. He said, 'What did you do? What the hell is power metal? I can't believe you did such a stupid thing. We can't use these cards with the words power metal on it.'"
