In late November 2007, the Swedish newcomers embarked on a tour with Himsa and Amon Amarth. The band also participated in the "Darkness Over X-Mas Tour" with Caliban and Heaven Shall Burn, and toured extensively across Europe with Dark Tranquillity and Soilwork. Sonic Syndicate played several European festivals and, in the winter of 2007, accompanied Amon Amarth as they toured stateside. The band played at the 2007 Wacken Open Air Festival. The singers of Sonic Syndicate, Richard Sjunnesson and Roland Johansson, also sang for a compilation album, called Nuclear Blast All-Stars: Out of the Dark with Soilwork guitarist Peter Wichers. A video was made for the lead single, "Denied", with renowned producer Patric Ullaeus. The new album was titled Only Inhuman and was released on. In November 2006, they entered Black Lounge Studios to record their follow-up to Eden Fire with Jonas Kjellgren of Scar Symmetry. 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. 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". In the summer of 2006, the band entered into a contest held by Nuclear Blast. The band completed the tour, then began demoing new material in early March. 2006 also saw the arrival of Roland Johansson as a permanent member. Kristoffer was replaced by John Bengtsson, whilst lead guitarist Roger Sjunnesson took over on keyboards. In early February 2006, during their tour with Avatar, both drummer Kristoffer Bäcklund and keyboardist Andreas Mårtensson were asked to leave the band due to lack of interest and musical differences. The band toured extensively throughout Sweden in support of Eden Fire, alongside such bands as Avatar. Eden Fire would go on to sell over 10,000 copies by the end of 2010 because of a re-release through Koch Distribution in the US in collaboration with France's Listenable Records. Bassist Karin Axelsson replaced Svensson in 2004 before the band changed its name to Sonic Syndicate and released its debut studio album, Eden Fire. They recorded three demo albums, Fall From Heaven, Black Lotus, and Extinction before signing with Pivotal Rockordings in 2005. This led to the forming of Fallen Angels in 2002 together with Andreas Mårtensson, Magnus Svensson and Kristoffer Backlund. In 2002, the brothers Sjunnesson eventually decided to break away from the band in order to focus on various other aspects of music.
