It is no secret that the Grateful Dead were pioneers of the LSD movement of the 1960s. However, after some years, Jerry Garcia preferred to not play under the influence of powerful psychedelics. In a classic 1994 interview — one of his last ever before his death just a year later — Jerry tells a funny story of inadvertently taking way too much acid before a concert in the late 60s, via a birthday cake containing 800 hits, and thinking the mafia was out to get him! Listen to his awesome retelling of the tale below.
