During the Golden God awards, previous Slipknot drummer Joey Jordison publicly disclosed the reason why he had to leave the band. It came down to a a neurological disorder by the name of transverse myelitis. Here’s what he had to say in regards to this:
Towards my end of my career in Slipknot—and I want you all to give praise to them as well. We accomplished a lot in life, every one of them, and I wish them nothing but luck and the best of praises.
What we created, in the basements of Des Moines, Iowa, will never be matched. It’s one thing that’s fucking absolutely unbeatable. I love those guys very much.
I got really really sick with a horrible disease called transverse myelitis, I lost my legs. I couldn’t play anymore. It was a form of multiple sclerosis, which I wouldn’t wish on my worst enemy.
I got myself back up, and I got myself in the gym and I got myself back in fucking therapy, to fucking beat this shit. And, if I could do it, you could do it. It’s the hardest thing I’ve ever done in my life, more than fucking anything. To people with multiple sclerosis, transverse myelitis, anything like that, I am living proof that you can fucking beat that shit.
And, fucking metal and all of these fans will do it for you. This is the fucking world ride right here. Thank you so fucking much. To my lady, Amanda! You can beat this shit, no joke. Just the fact that metal lives in your heart, you can fucking accomplish anything.
