From Conrad Knickerbocker’s interview of William S. Burroughs in “The Art of Fiction No. 36” (The Paris Review: Fall 1965, No. 35):
I felt that heavy metal was sort of the ultimate expression of addiction, that there’s something actually metallic in addiction, that the final stage reached is not so much vegetable as mineral. It’s increasingly inanimate, in any case. You see, as Dr. Benway said, I’ve now decided that junk is not green, but blue.
