And there are some that would say this is a good thing. They would point out the tragic examples of Barrett, Roky Erickson and Tommy Hall of the 13th Floor Elevators, Brian Wilson, Daniel Johnston, Skip Spence, and Jeremy Spencer and Peter Green of the original version of Fleetwood Mac, and they would say that LSD was a drug to be avoided at all costs, even before they got around to remembering the Manson "family." And if they pointed out that inherently creative people had the most to fear from taking LSD, I would have to agree.

And yet I would have to say that the anti-acid crowd is dead wrong, at least as far as aesthetics are concerned.

Look, musicians are going to do drugs. They always have and they always will. And sure, acid has claimed a few prominent people. I think there's a certain threshold we all have within us for acid, and when you cross it, you have successfully destroyed your ego. Which may or may not be fine for you, but it sure is hell on those who love you. But in any case, you could come up with longer lists of musicians destroyed by any number of other drugs. Hell, there are probably more musicians who died through the abuse of prescription drugs -- Hank Williams and Elvis, to name two -- than there are acid casualties. And heroin, booze and cocaine have claimed a few too, as I seem to recall. What's more, the acid-heads tended to leave prettier musical corpses than the junkies or drunks.

We're in uncharted waters now. Very few of the younger bands on the Billboard modern rock charts, groups like Taking Back Sunday, Angels & Airwaves, Panic! at the Disco and 30 Seconds to Mars, sound like they have ever dabbled with acid, or anything else that truly bends the mind.

Nope, this is music by and for the Ritalin Generation, from their over-amped central nervous systems straight to yours. The dry-mouthed singers all whine about their parents, bosses and lovers, and the list of adjectives you would use to describe the music of these bands is uncannily similar to a list of the side effects of Ritalin use: "jittery," "irritable," "depressed," "anxious," "paranoid," "repetitive."

None of which are too terribly pleasant-sounding for those of us who lack Ritalin scrips.

Contrast that with acid, the cornerstone on which much of rock and roll has been based from about 1965 through about 1974. That music, as well as that which still follows in its wake, soared and vaulted. And as stupidly nave as it seems today, the singers in those bands wanted you to think great thoughts about the cosmos, saving the planet and your immortal soul.

"Ritalin and Adderall and those drugs are all about focusing," says Kurt Brennan, a co-owner of the psych music-friendly record store Sound Exchange. "Acid is more about unraveling."

Without LSD, there would have been no Pet Sounds, no Revolver, and no Are You Experienced. There would also have been no MC-5, no Parliament-Funkadelic, and no Sly and the Family Stone. And of course, no Pink Floyd or 13th Floor Elevators either.

And think about what wouldn't be were it not for those bands. Were it not for MC-5, there would be no punk; were it not for Sly Stone, there would be no Prince; were it not for Floyd, there would be no Radiohead. And a world without Revolver and the recordings of Jimi Hendrix scarcely bears thinking about.

This is not to argue that LSD is some kind of panacea. Great music exists outside its orbit, and its own excesses can be documented not only in the burnouts it helped along on the road to madness and/or hermits' lives, but also in music. The interminable noodling of the Grateful Dead comes to mind, as does the ridiculous bombast of bands like Yes, the Moody Blues and King Crimson, all of whom contributed mightily to the rise of punk.

I don't mean to say they contributed directly to punk, of course. What I mean to say is that acid-drenched slabs of ludicrous musical pomposity such as "Nights in White Satin," "Yours Is No Disgrace," and that "Tarkus" malarkey from Emerson, Lake and Palmer fairly cried out for a short, sharp kick in the nads from the likes of the Ramones, New York Dolls and Sex Pistols, one that came too late, alas, to save us from the likes of Kansas and Styx. And yet even the art-rock movement also laid the foundation for New Wave and electro-pop through disciples like Brian Eno, Kraftwerk and Tangerine Dream.
