Silicon was released initially as an mp3 download as part of NPG Music Club Edition # 11, although a clip of the song had been included nine months earlier as part of NPG Ahdio Show # 2. In 2002, Silicon was offered again (with no explanation) as one of only two mp3 downloads offered in the second year of the NPG Music Club. In 2004, an edited version of the track was included as the opening track on the compilation album The Slaughterhouse (the first line of the song is "welcome 2 the slaughterhouse").
Recording dates are unknown, but the first verse is largely taken from The Greatest Romance Ever Sold (The Adam & Eve Remix), which may suggest the track was recorded shortly after that remix, in late 1999 or 2000 (most likely at Paisley Park Studios in Chanhassen, Minnesota). Some lyrics from the track ("don’t you know dead blood kills interferons?") were later quoted in the live version of Xenophobia, released on the live album One Nite Alone... Live!
