Cover art for Arcarsenal lyrics by At the Drive-In

Um, it's about drug use, abuse, addiction:

soft white glow in the cranium a bulls eye made sedated

a catatonic leisure at 1000 miles per hour

so who's in charge here barking out loud so clear because i'd really like to meet him

If you've ever done heroin (opiates) you know exactly what this means.
