Before the Summer of Love commercialised consciousness expansion, this Austin quintet weaponised garage rock fury with Tommy Hall's amplified jug wailing like a malfunctioning conscience. Released October 1966, it's the first album to brand itself "psychedelic" and means it, from Roky Erickson's feral howl on You're Gonna Miss Me to the philosophical dread of Reverberation (Doubt).

Where San Francisco would soon package acid trips for mass consumption, the 13th Floor Elevators offered something genuinely unhinged, a confrontational vision that anticipated punk's raw nerve more than Haight-Ashbury's flowers.
