In the stunning Californian desert, Iggy Pop joined forces with Joshua Homme to create what might be Pop's final album. Co-directed by Homme himself and photographer Andreas Neumann, this is the fascinating story of that collaboration, a musical adventure told with luminous visuals. A kaleidescope film about the creative process, this is also a thoughtful meditation on the inescapable fleetingness of time. (Sheffield Doc/Fest)
