As of 2012, Metallica guitarist Kirk Hammett had recorded 400 new guitar riffs for the band’s next album. As of six months ago, Kirk was down to 158 of those potentially wicked shreds due to the loss of his iPhone.

“I put riffs on my iPhone, but something very unfortunate happened to me about six months ago. I lost my iPhone [containing] 250 musical ideas. And I was crushed. It didn’t get backed up,” Hammett told Jamey Josta in the latest episode of The Jasta Show.

But wait, it gets worse, “I can only remember, like, eight of [the ideas]. So I just chalked it down to maybe it just wasn’t meant to be and I’ll just move forward with it.” he continued.

I think it’s fair to say that he’s pretty zen about losing 242 guitar riffs. Regardless of the loss, the new album is still slowly rolling forward, and Kirk had this to say about the album’s sound, “It’s a lot similar to Death Magnetic but different in certain parts. And, you know, there’s a couple of songs that remind me of something on And Justice for All, but the album doesn’t sound like And Justice for All.”

Now if I could give some personal tech advice: Look, James, Lars, Kirk, Robert, all of Metallica, if you’re going to record sweet new licks on your iPhone, you have to ride the lightning… cable to the usb port, open iTunes and hit “back up iPhone” so this will never happen again.
