Theoretically Pure Anterograde Amnesia

Theoretically Pure Anterograde Amnesia (stylized as “Theoretically pure anterograde amnesia”) is the fourth studio album by the Caretaker, an alias of musician Leyland Kirby. Released in 2005, it abandoned the haunted ballroom aesthetic of the previous albums and explored memory loss. Divided into six CDs, it consists of seventy-two drone tracks combined to create an almost four hour long release. It was compared by several critics to other musicians, including Merzbow, Boards of Canada, and Krzysztof Penderecki.

The liner notes for Theoretically Pure Anterograde Amnesia were written by Mark Fisher. The blogger, who referenced the record on his book Ghosts of My Life (2014), died by suicide in 2017, for which Kirby created Take Care. It's a Desert Out There.... Theoretically Pure Anterograde Amnesia was met with general praise from music critics, who felt it improved on the Caretaker's style. However, some of the tracks were criticized for their production. The album has since been considered a precursor to the Caretaker's final and most acclaimed project, Everywhere at the End of Time.
