After a ten-year hiatus, Sutton formally relaunched Bark Psychosis in 2004 and revealed that he had, in fact, been recording new Bark Psychosis tracks since 1999 with various collaborators. The project was now, in effect, a Graham Sutton solo project in all but name, with Sutton playing the majority of the instrumentation himself. Former band drummer Mark Simnett was present, but only in the form of unspecified sampled drum tracks. Sutton's most prominent collaborators were now Colin Bradley (better known as the guitarist from Dual) and the former Talk Talk/.O.rang drummer Lee Harris. Other contributors to the project were Anja Buechele (the singer for The $urplu$), bass player David Panos, New Zealand multi-instrumentalist Rachel Dreyer (piano, vocals, wood flute), Shaun Hyder (Sindhi tamboura), Alice Kemp (bowed guitar) and T.J. Mackenzie (trumpet). One of the clearest indications that the project had changed was that Sutton was now sharing his lead singer's role with others: Buechele and Dreyer covered many of the vocals, sometimes even singing entire songs. Conversely, a link with the past came from Pete Beresford who contributed vibraphone, reprising his role on "Hex".
