Metallica’s Kirk Hammett has 767 riffs written for the band’s next album

During a new interview with Rolling Stone, Metallica guitarist Kirk Hammett revealed that he has quite a bit of riffs written for the band's next album. According to him, he has "767 new ones."

Hammett said the following:

I have 767 new ones for the next album. It is such a nightmare going through this stuff, too. And I'm the one responsible for all of it and I can't do it…. I don't foresee us starting the next album for at least another year because we're still finishing the tour. Once we fully finish this and go to all the outlying places like Asia and Australia and New Zealand, I think we're gonna take a little bit of a break, not too much of one, and then we're gonna get right back into it.

He also added the following about his upcoming solo album:

I'm just actively getting ideas together for my [first] solo album. I guess the best way to describe it is it's gonna be a fusion of all sorts of styles…. All of a sudden I'm writing classical progressions, and all of a sudden I'm writing more heavy stuff and all of a sudden I'm writing like a funk thing…. There will be vocals because the songs that I wrote scream for vocals this time around.

So I'm like, okay, who's gonna be doing the vocals? I don't know. I hope I'm not—I already have too much to do on stage… I have an instrumental piece that to me sounds like it's 2000 years old called 'The Mysterion.' It's based on all this stuff that I've been reading, the ancient Greek texts, and it's amazing to me because I wouldn't have had this instrumental if I didn't start reading these ancient texts.
