about the wikipedia tip, thanks. I'll send them my recollections on the matter. That's an interesting site. I had forgotten about the Burroughs use of "heavy metal" in another context.

A lot of things coalesced in 1968, as the light optimism (in some quarters, anyway) of 1967 crashed and burned during heavy, doom-and-gloom 1968. No wonder that a corresponding musical style and the name for it evolved rapidly. Early in 1968 I wandered past the door to the East Village Other NYC underground newspaper and noted he door a sign reading "flower power is dead. Long live firepower."
