In the summer of 2006, the band entered into a contest held by Nuclear Blast. They sent in their self-titled demo "Sonic Syndicate", which included early preproduction versions of the songs "Psychic Suicide", "Blue Eyed Fiend", "Callous" and the album version of "Jailbreak". Out of over 1,500 competing bands, Sonic Syndicate was chosen as one of three winners and offered a new recording contract with the label. In November 2006, they entered Black Lounge Studios to record their follow-up to "Eden Fire" with Jonas Kjellgren of Scar Symmetry. The new album was titled "Only Inhuman" and was released on 18 May 2007. A video was made for the lead single, "Denied", with renowned producer Patric Ullaeus.
