The Paradigm Shift is a fitting title for Korn's new album. Not only has lead guitarist and co-founder Brian "Head" Welch returned to the metal outfit after an eight-year hiatus, but frontman Jonathan Davis tackled writing the album while coming off of a rehab stint that sounds almost as mind-altering as an actual drug.

"I was in a straight haze," Davis told Rolling Stone about writing the band's upcoming 11th album. "I detoxed off that medication, it was an anti-depressant. I'd been on it for three years and the doctor told me, 'You gotta get off this, it's bad for you.'" 

But instead of going to the Betty Ford clinic or one of the other chic rehab joints favored by celebrities, Davis went to the boonies to kick his medication addiction. "I went to this county rehab. I was like, 'I don't want to do this sh-t ever again' so I went into the most ghetto, f--ked-up place I could find and I'm barely coming out of it now."

For those keeping track of the timeline, that means The Paradigm Shift came out of that mindset. "It was stream of consciousness," Davis explained. "So many songs I don't know what the f--k I'm talking about… I don't know how the hell I did it. I was so f--ked up from coming off all that medicine and I feel so good about the record. When I look back now, I'm like, 'Wow, how did I come up with this sh-t?'"

We'll find out what Davis' rehab haze sounds like—and if this new material contains any of the electronic elements Korn flirted with on their last album—when The Paradigm Shift drops on October 1.
