'It was 52 years ago today back in 1965 that a hell of a strange trip began. . . , and Uncle Ken taught the band to play.
The first ever event called an Acid Test — featuring a rock band of misfits called The Warlocks, who a couple weeks later would change their name to The Grateful Dead. Held at Ken Babbs' house. This is most likely the only poster ever made for the event (hand drawn).'
