Welcome back to Psychobabble's Psychedelic 500, in which I count my personal fave psych songs from 500 all the way down to #1! Today, let's see what's sampling the brown acid from 275 to 251...
275. The Byrds- "5D (Fifth Dimension)" (1966), in which The Byrds trip so hard that they pass right through the fourth dimension, which is vectors, and into the fifth one, which has freedom, which, honestly, is a much easier concept to grasp than vectors.
