It's All In Your Head FM v1.0 is a 2006 album by the sound collage band Negativland.

It was compiled from a series of live recordings made by the band in California (San Francisco and Los Angeles) in October 2005.

The series was also called "It's All In Your Head", and its theme was to propose, and provide evidence for, the case that there is no God.

It is hosted by Don Joyce in one of his many alter egos, that of Dr. Oslo Norway, chairman of One World Advertising.

An entirely new version of the work, culled from different performances recorded to multi-track and carefully re-crafted in the studio, was released in September 2014, simply titled It's All In Your Head.
