Battlefield Earth served as the inspiration for the first-ever musical soundtrack to a book. Aptly titled Space Jazz and reflecting the mood of a future Earth grown primitive following an alien assault, the album offers thirteen compositions by L. Ron Hubbard based upon significant events and characters from the novel. To best convey the cross-cultural sweep of the novel, the album utilized elements from several genres—from honky-tonk and free-swinging jazz to cutting-edge electronic rock. The result was a wholly new dimension in space opera sound, and what critics declared as a most “auspicious recording debut.”
Reflective of a lifelong commitment to world peace, lyrics from Battlefield Earth’s “Declaration of Peace” were reprinted on thousands of parchments and bestowed on Ron’s behalf to those organizations dedicated to the same ends.
