LSD criminalization in 1966 coincided with a radical Los Angeles band influx

Evidence

LSD was made illegal in the US on October 24. Soon after, Leary got into a dispute over money with the Village Theater (“We have been driven from the temple,” he told the Voice) and moved the November 1 performance of Reincarnation of Jesus Christ to the Village Gate. Scarcely had the Velvets left the Balloon Farm when the two most radical Los Angeles bands, the Doors and the Mothers (rebranded, under pressure, the Mothers of Invention), made their New York debuts. — J.
