What elements make up a psychedelic song-be it rock, pop or folk, British or American, East or West Coast? 1960s artists didn't categorize the music. They were just pushing the envelope-lyrically, musically, technologically-while ingesting the necessary chemicals. So, differentiating between the authentic, borderline and phony is a largely subjective topic, as revealed in this episode's acid-drenched discussion between Richard, Erik, Allan and Craig. And there's also a brief cameo by Donovan.
