Psychedelic rock was born in a perfect storm of paradigm shifts that reshaped pop culture in the mid-’60s: the expanded technological capabilities of the recording studio; the rapid maturation of rock ‘n’ roll from teen dance music into an experimental art form; and, yes, the increased availability of hallucinogenic drugs. We’re still feeling the aftershocks. The tape-splicing manipulations of The Beatles provided a blueprint for the sound-collage surrealism of Animal Collective, while the interstellar overdrive of Pink Floyd and The Jimi Hendrix Experience inspired the likes of My Bloody Valentine and Tame Impala to venture deeper into the unknown.
