Psychedelic Shack (1970) by The Temptations is the album which represents the bands’ full-blown submergence into psychedelia. Completely written by Norman Whitfield and Barrett Strong, Psychedelic Shack almost completely abandoned the “Motown Sound” formula; hard rock guitars, synthesizer sound effects, multi-tracked drums, sampling, and stereo-shifting vocals give most of the album’s songs a harder, less traditional feel than The Temptations' previous work.
