The final music that was ever recorded by Christopherson occurred in Bangkok, Thailand with a project named "Electric Sewer Age" that also involved musician Danny Hyde. The original intention of the recordings was to complete a series of releases called "Moons Milk", but an album called "In Final Phase" was eventually released in 2013, with only 999 numbered CD copies made available. The CD is packaged in record sleeve-style thickened cardboard, and each copy is numbered from 1 to 999, while the insert sleeve displays a picture of Christopherson in his Bangkok studio that was taken at the moment that the recording was completed.
