April 19th, which is this Friday, marks an odd holiday known as Bicycle Day — the day, now 81 years ago, when Swiss scientist Albert Hofmann rode his bike home from work after dosing himself with his lab concoction, lysergic acid diethylamide, or LSD. The first acid trip.Hofmann’s wobbly ride is what launches us into an exploration of a moment, when Ken Kesey, an evangelist of acid would emerge from a Menlo Park hospital lab, and plow through the nation’s gray flannel culture in a candy colored bus. Some know Kesey as the enigmatic author behind One Flew Over the Cuckoo’s Nest — others, as the driving force in The Electric Kool-Aid Acid Test, Tom Wolfe’s seminal work in New Journalism. In honor of the 50th anniversary of the release of Acid Test, Brooke speaks with Wolfe and writer River Donaghey about how acid shaped Kesey, spawned the book and de-normalized American conformity.Songs:Holidays B by Ib GlindemannIm Glück by Neu!Apache '65 by Davie Allan and the ArrowsSelections from "The Acid Tests Reels" by The Merry Pranksters & The Grateful DeadAlicia by Los MonstruosThe Days Between by The Grateful Dead (Live 6/24/95)  On the Media is supported by listeners like you.
