The decision to remove Ziller from Bonfire began to show on Lessmann, who had remained in the band. After many attempts to break through in the North American scene and what he thought was a disappointing fourth album, Lessmann left the band on 25 September 1992. His announcement was not a total shock to the rest of the band, but it did leave them with the dilemma of who would take his place. One vocalist that had the group's attention was Michael Bormann, who was singing for Letter X and had his own side-group called Jaded Heart. Moreover, he was previously in High Voltage and the J.R. Blackmore Group. Even though he was willing to sing with Bonfire, he was committed to his other two projects so the group continued looking. The unsuccessful attempt to find a full-time vocalist led to Bormann becoming the new frontman of Bonfire in March 1993. Although he did leave Letter X, he maintained his band Jaded Heart.
