Peter Green in memoriam

[LeoL]

The legendary "LSD chef" of the Grateful Dead was Owsley "Bear" Stanley (1935–2011). It was here that the fateful connection that led to the collapse of Peter Green's mental health.

Although Owsley was officially known as the band's sound engineer and "fifth member", he was first and foremost a world-famous underground chemist who produced most of the purest LSD of the mid- to late-1960s.
Owsley Stanley's importance

Massive production: He is estimated to have produced over a million doses of LSD, which were widely distributed through "Acid Tests" and Grateful Dead tours.

"Owsley Blue": The substance he produced was known for its exceptional purity at a time when there was a lot of impure stuff on the market.
Pioneer in sound: In addition to chemistry, he revolutionized the sound of rock concerts. He designed the band's massive "Wall of Sound" speaker system.
