On January 24, 2011, Agent Steel announced that Cyriis would not perform with the band on the 70000 Tons of Metal cruise due to "unfortunate events". Helstar vocalist James Rivera and Steel Prophet vocalist Rick Mythiasin would fill in for him, in which they would perform as Masters of Metal. On February 24, 2011, the band would cancel their appearance at the Keep It True festival in April. The organizers of the event explained that they were "facing totally new demands from one part of the band, that we, as a still small and dedicated festival, could not meet and really also do not want to meet. This, plus the troubles within the band itself, led to the final cancellation of Agent Steel with John Cyriis." Guitarist Juan Garcia denied any rumors that Rick Mythiasin was the band's new vocalist, but was only a temporary fill-in for Cyriis. Due to the circumstances surrounding the band, the organizers invited Agent Steel to still perform, but under a different name, and that Mythiasin would be invited to perform onstage with them. Cyriis later returned to the band and performed at the Sweden Rock Festival, which was claimed to be his final performance with the band, but was refuted by Cyriis during the event. Despite his apparent return, he would perform with his band S.E.T.I. at the Headbangers Open Air festival in July.
