Mark Bell, Mike Patton, Robert Wyatt, Japanese accapella Dokaka, Inuit throat singer Tanya Tagaq Gillis and human beatbox Rahzel all guest on the album.

Yeah, they all fell into place one by one. I’d already worked with Tanya and Mark Bell on the Vespertine tour and Mike Patton introduced me to Dokaka and Rahzel. When I realised the album was becoming a vocal record the musical fascist in me decided using any MCs or vocal percussionists would be too cheesy. I changed my mind when I saw Rahzel freestyle a whole Kraftwerk track without pausing for breath. He came to the studio to lay some beats a few days later and ended up singing on the whole album. Everytime he tried to leave I’d beg him ‘Just one more, just one more !’, 18 august 2004
