512 (song)

Blythe wrote the lyrics for the song, in Pankrác Prison cell number 512, while in custody during his manslaughter case. The song is was about contemplating how the experience was changing him. According to Blythe, most of his time was spent in a basement dungeon. He said the guards put him there so they could monitor him for depression. "They stick you in the worst, dimmest, darkest place in the prison," he says. "I couldn't even see the sun to tell what part of the day it was. It was just steadily lessening levels of gloom."^[3][4]
