Korn have been teasing a new album for months now and the anticipation just hit new heights. Promising their heaviest record in years, the band upped the ante and revealed that Slipknot frontman Corey Taylor has provided guest vocals on what will become a "fan favorite" according to guitarist James 'Munky' Shaffer.

Speaking with Metal Hammer, Munky said, “We have Corey singing on one track and it’s going to be a fan favorite because he really lets loose. On a heaviness scale of one to 10 with 10 being the 1994 self-titled, this album is a definite nine.”

The axeman went on to detail how guitarist Brian 'Head' Welch's return to the band in 2013 has made things easier overall. “When Head came back to us on the last record, it was our way of getting the wheels greased," Munky detailed, adding, "Now everything is well-oiled and the machine works really well. When Head and I start writing riffs together, we have this endless stream of creativity — we’re like Korn’s yin and yang."

Head left Korn in 2005, though he said he was asked to rejoin the group every numerous times by the band's management, telling Rolling Stone, “I would do book signings, and they would send someone to say, ‘Hey, it would be cool to have you back one day.’ My daughter would be here, and at 8, 9, 10 years old, she would say, ‘No way, Dad. You can’t go back to that band.'”

Korn are currently out on a summer co-headlining tour with Rob Zombie. The run will extend through Sept. 3, leaving the band three weeks off before picking it back up for a co-headlining run with Breaking Benjamin from Sept. 24 through Oct. 19. Slipknot are also on a co-headlining trek of their own, featuring Marilyn Manson. A full list of stops for both tours can be found at our 2016 Guide to Rock + Metal Tours.
