#1 is the first full length album by electroclash duo Fischerspooner released in 2001. It originally received a limited run on International DeeJay Gigolo Records, and contained "The 15th", a cover of a Wire song from their album 154. #1 has been re-pressed several times with a different track listing. The title "Fucker" was also censored on subsequent releases, either as "!@*$%#", "*#!@¥¿", or "*#!@Y?".
"Sweetness", "L.A. Song" and "Megacolon", all from the re-issue were originally released together on an EP titled #1 Supplement that was discontinued in time for the first re-issue. A limited edition pressing from 2003 also included a DVD with several remixes, a documentary, as well as four videos—"Sweetness", "The 15th" and two versions of "Emerge".
#1 was included among a group of 15 DualDisc releases that were test marketed in just two cities: Boston and Seattle. The DualDisc version of the album is rare. It has the standard album on one side, and bonus material on the second side. The DualDisc release was never reissued after the very limited test market run.
