Psychedelic rock emerged in the mid-1960s, blending diverse influences like folk, blues, and Eastern music. It reflected the era's social upheaval, drug experimentation, and counterculture movement, challenging traditional norms and expanding musical boundaries. Key bands like The Beatles, Jimi Hendrix, and Pink Floyd pioneered the genre's sound. They used innovative studio techniques, unconventional instruments, and surreal lyrics to create immersive, consciousness-expanding experiences that captured the spirit of the times.
