IRO-bot is the hidden track on the 2002 album The Second Stage Turbine Blade. It plays after a period of silence on either Track 10 ("God Send Conspirator" on the 2002 original release) or Track 13 ("Everything Evil" (demo) on the 2005 re-release). On the live electric version played at Neverender, the song has a slightly altered structure and lyrics. This song is later reprised on the track "21:13". The line "the useless mend the fixed..." is referenced in the song "The Broken" on the album Year Of The Black Rainbow.
