• Beartooth's third album is a stark chronicle of frontman Caleb Shomo's battle with his own demons. He told Kerrang how the album's concept "literally hit me like a train" when he was on the road touring Aggressive in December 2016. Shomo recalled:
  
  "We'd already been on the road for a really long time, and I remember being in Finland, and I hadn't seen the sun in, like, a week. I was having a really hard time, and I was really depressed. In that moment I definitely felt suicidal again, which I hadn't for a very long time. And it all just... It all happened in that moment. I was like, 'Holy s--t, this is a disease, this will never go away, and I really need to learn how to cope with this and dive in deeper.'
  
  So I wrote down the word 'disease' and realized that was the name of the record, and the whole concept. Then I went home and wrote the song 'Disease.'"
• The song's music video was directed by Drew Russ, who has previously worked with Beartooth on their clips for "Lips," "In Between" and "The Lines."
