Reznor wrote the song after the extended play '' Broken '' ( 1992 ) was completed . It was initially a poem which he expanded into a full song . He later moved to a house famous for its status as the site of the gruesome Tate murders , on July 4 , 1992 , and created a studio space there , calling it Le Pig . When asked about the building where production on the song was done , Reznor responded that he chose it merely for space considerations , claiming not to have been aware of the house 's connection to the murders until after he chose it . " I looked at a lot of places " , Reznor said . " And this just happened to be the one I liked most . " The studio name , Le Pig , alludes to the word " PIG " written with Tate 's blood on the front door by the murderers , itself a reference to The Beatles ' song " Piggies " . This incident introduced Reznor to their 1968 album , the '' White Album '' , which included " Piggies " . The frantic drumming on the outro is Reznor 's only attempt at performing drums on the record , and one of the few " live " drum performances on the album . He had stated that the recording was from him testing the microphone setup in studio , but he liked the sound too much not to include it
