The album came about after David Gilmour released an online single, "Chicago - Change the World" (a re-titled cover of the
Graham Nash song "
Chicago"), in support of
Gary McKinnon. It was remixed by the Orb, who asked if Gilmour would provide some extra guitar parts. These were recorded in one day in June, 2009, at
Youth's
Wandsworth studio, the Dreaming Cave, resulting in a 25-minute track. Youth and the Orb expanded this to the eventual album. It was produced by Youth and engineered by Tim Bran (of
Dreadzone) and David Nock. Mixing was done by Youth, with mix engineering from Bran, Nock and Michael Rendall at "The Study" in 2010. Mastering was done by Andy Baldwin at Metropolis Studios in
London. A headphone version was released as the second disc of the deluxe 2-CD edition, with
sound design by Mike Brady, recording by Mike Brady, David Nock and Michael Rendall, and mixing by Youth. == Track listing ==
