On December 12, 2013, the band announced through its official website that Joey Jordison had left the band after 18 years, citing personal reasons.<ref>{{cite magazine|url = https://www.billboard.com/music/music-news/slipknot-drummer-joey-jordison-part-ways-5839723/|title = Slipknot, Drummer Joey Jordison Part Ways|magazine = Billboard|first = Kevin|last = Rutherford|date = December 13, 2013|access-date = February 8, 2022}}</ref><ref>{{cite news|url=https://www.theguardian.com/music/2013/dec/13/drummer-joey-jordisonleaves-slipknot |archive-url=https://web.archive.org/web/20160321144446/http://www.theguardian.com/music/2013/dec/13/drummer-joey-jordison-leaves-slipknot |archive-date=March 21, 2016 |title=Slipknot drummer Joey Jordison leaves band |newspaper=The Guardian |date=December 13, 2013 |access-date=December 14, 2013 |url-status=dead }}</ref><ref>{{cite magazine|url = https://www.nme.com/news/slipknot/74397|title = Drummer Joey Jordison leaves Slipknot|magazine = NME|date = December 13, 2013|access-date = December 14, 2013}}</ref> On his official Facebook page, Jordison later said he "did not quit Slipknot" and that he was "shocked" and "blindsided" by the news. Both Jordison and Slipknot independently promised to release further details about the split.<ref name="Jordison">{{cite web|url = http://www.metalinjection.net/latest-news/drama/joey-jordison-i-did-not-quit-slipknot|title = Joey Jordison: 'I Did Not Quit Slipknot'|publisher = MetalInjection|first = Greg|last = Kennelty|date = January 2, 2014|access-date = January 9, 2014}}</ref> Taylor said Jordison would not be appearing on the new album because he did not participate in any songwriting sessions before his departure.<ref>{{cite magazine|url = http://loudwire.com/corey-taylor-first-interview-joey-jordison-departure-slipknot/|title = Corey taylor gives first interview following joey jordison's departure from slipknot|magazine = Loudwire|first = Graham|last = Hartmann|date = December 13, 2013|access-date = December 14, 2013}}</ref> After years of both sides being silent and evasive as to the reasons for his leaving the band, Jordison revealed in June 2016 that he suffered from [[Transverse myelitis]], a neurological disease that cost him the ability to play the drums toward the end of his time with Slipknot. However, Jordison played drums in the blackened death metal act [[Sinsaenum]], which he joined in 2016.
