 Following a UK tour supporting US technical metallers Byzantine, 2005 saw the band's first line-up change with the departure of bassist Carl Davis, replaced by Liam Durrant (formerly of UK Hardcore band "Freebase" and "Violation").Further changes followed in 2006 after UK tours with Maltese metalcore band "Slit" and French deathgrinders "Happy Face", with the departure of guitarist Noel Davis, and with Liam taking time out to pursue a university course.With Neil Hudson taking on guitar and vocals, and new bassist Glen Pywell (from deathgrind/doom band The Atrocity Exhibit), Gutworm recorded their second full-length album "Disfigured Narcissus", again with Greg Chandler, which was released to critical acclaim on Anticulture Records in October 2007.
