A guy I speak to from time to time went to last night’s Sleigh Bells concert at Manhattan’s Terminal 5. Which is obviously fine but he also “dropped,” if you catch my meaning. Can you imagine being in this kind of sensory-onslaught environment and going “whoo-hoo!” and raising your pointed index finger in tribute while tripping?

I wrote the guy back this morning and asked, “Sorry to sound like I’m sounding but have you ever thought about looking at LSD the old-fashioned way — as a chemical additive that opens the doors of perception and leads to a parting of the clouds and, for the true seekers, spiritual satori?

“I don’t need to remind you that thousands if not tens of thousands of lives were profoundly affected by LSD during the latter half of the 20th Century. LSD changed a portion of the Harvard University faculty in the early ’60s as well as the music of all the best rock bands of the mid to late ’60s (‘I know what it’s like to be dead’), and it triggered the great spiritual awakening of the late 1900s (roughly 1965 to the late ’70s) and…let me get this straight…you’re dropping it in order to ‘party’ and go whoo-hoo at a Sleigh Bells concert?

“Have you ever heard of Jay Stevens‘ “Storming Heaven,” the book I’ve written about in the column?

“I’m only saying that LSD opened things up spiritually and perceptionally for a whole lot of people in the ’60s and ’70s and gave them a taste of the mystical and sublime, the kind of Eastern enlightenment God-head that had previously been known only to a very select crowd (Aldous Huxley, Hermann Hesse, earnest readers of “Bhagavad Gita” and “Siddhartha,” the mystics of India, Cary Grant, Timothy Leary).

“What form does LSD come in now? Tablet, capsule…? How long does it last? For me the first two or three hours would be ecstatic — ‘elevator in the brain hotel’ — and then it would gradually level out and sink down after eight or ten hours.

“‘Elevator in the brain hotel‘ is great, but there’s SO MUCH MORE to be had from that drug….words fail.”
