4.0 - Considering some other 1967 releases ("Sgt. Pepper's", "Velvet Underground And Nico", Doors' debut, "Surrealistic Pillow", "Are You Experienced") it's no wonder this records feels like a footnote. Still, it certainly outshines other albums within the psychedelic canon (see "The 13th Floor Elevators"). This feels like a complete and cohesive artifact of the Haight-Ashbury sound and there are genuinely trippy, LSD-laden jams. Particularly, "Porpoise Mouth" and "Section 43" create a swirly, colorful atmosphere in the middle. "Bass Strings" is also a highlight.
