[citation needed] Many of the lyrics were heavily influenced by Stephan's divorce with his ex-wife Cathrine and the relationship with their daughter Iben.

Alon was also thought to have been responsible for much of the album's distinctive sound, though Stephan still retained a high degree of artistic control.

For the tour and for Apop's third single "Unicorn", he was replaced by Angel, a former Kovenant guitarist who helped give the same aggressive attitude on stage.

The Harmonizer tour took Apop all over the world, even into more dangerous zones such as Israel where they performed "Non-Stop Violence" to an ecstatic crowd of fans.

A concert at The Grosse Freiheit in Hamburg, Germany was filmed and released on a DVD along with a documentary and all the videos from the album called The Harmonizer DVD which also included the Unicorn EP, which included a new video version of the track which was a stylistic change as it added drums and guitar on top of the original track.
