It is an alternate soundtrack to the 1972 science fiction film, Silent Running.

It was originally commissioned by Glasgow Film Festival at the beginning of 2011 as a live re-score performed by the band.

In July 2011, the band announced their intention to fund a studio recording of the Silent Running soundtrack by raising $7500 through the crowd-funding website Indiegogo.

By the end of the funding period they had raised over $27,000.

[4] Silent Running was released in mid-November 2011 as a numbered, limited edition vinyl LP to those Indiegogo funders who had paid for this option, and as a digital download from the band's website.
