Lars Ulrich recalled first hearing Guns N' Roses back in the day and admitted that his mind was completely blown by the style, power, and passion of Appetite For Destruction.

The Metallica drummer told Spin, "I was sitting on the airplane going through a bunch of cassettes that I finagled over at our record company, and one of them was Appetite. When 'It’s So Easy,' the second song, came on, it just blew my f***kin' head off."

Ulrich went on to remember, "I had never heard anything with that kind of attitude. It wasn’t just what was said — it was the way Axl (Rose) said it. It was so venomous. It was so f***ing real and so f***ing angry."
