Forty-six years ago today, rock and roll got a hell of a lot weirder in the state of Texas. On Nov. 30, 1966, Austin garage band The 13th Floor Elevators released their The Psychedelic Sounds Of album on Houston's International Artists label. Powered by the raw, fluttering classic "You're Gonna Miss Me," the record helped fuel an acid explosion in rock from Buffalo Bayou to San Francisco Bay.

This is a record that still sounds edgy and unbound today. In 1966, it must have sounded shocking.
