Rivers previously said of the inspiration for going metal on Van Weezer: "We just noticed over the last few years there’d be these moments during the show where I’d accidentally bust out a few harmonics or a whammy bar dive or a little tapping just because I can’t control myself.
"And we noticed unlike in decades past, now the audience would go ballistic whenever they’d hear even a hint of that style. So I started doing it more and more. And soon I’m just like shredding through the whole show and we’re like, 'Jeez, we should make an album like this.'"
Van Weezer is due out on May 7 via Crush Music / Atlantic Records.
