Porcupine Tree originated in 1987 as a collaborative hoax project by Steven Wilson and Malcolm Stocks. Partially inspired by the psychedelic/progressive bands of the 1970s, such as Pink Floyd, that had dominated the music scene during their youth, the two decided to form a fictional legendary rock band named The Porcupine Tree. The two fabricated a detailed back-story including information on alleged band members and album titles, as well as a "colourful" history which purportedly included events such as a meeting at a 1970s rock festival and several trips in and out of prison. As soon as he had put aside enough money to buy his own studio equipment, Wilson obliged this creation with several hours of music to provide "evidence" of its existence.^[6] Although Stocks provided a few passages of treated vocals and experimental guitar playing, his role in the project was mostly offering occasional ideas, with the bulk of the material being written, recorded, played and sung by Wilson.

At this point, Porcupine Tree was little more than a joke and a private amusement, as Wilson was concentrating on his other project, No-Man, an endeavour with UK based singer and songwriter Tim Bowness. However, by 1989 he began to consider some of the Porcupine Tree music as potentially marketable. Wilson created an 80-minute-long cassette titled Tarquin's Seaweed Farm under the name of Porcupine Tree.^[7] Still showing the spirit of his joke, Wilson included an 8-page inlay which further revealed the hoaxed Porcupine Tree backstory, including references to fictitious band members such as Sir Tarquin Underspoon and Timothy Tadpole-Jones.^[8]
