 In 2004, the band took a break while planning their next moves, writing the follow-up to Challenger and working on an experimental remix album (Alter, with contributions from Justin Broadrick, Mick Harris, Dalek, Francisco López, Asmus Tietchens).Terraformer was recorded in late 2004 in Geneva, engineered by their friend Jerome Pellegrini (former Nostromo guitarist, now in Mumakil).Originally meant to be a demo of the album, the session proved satisfactory enough for a proper release.
