The album was among the first to make prominent use of the
Buchla synthesizer, which was previously featured on
Morton Subotnick's 1967 recording
Silver Apples of the Moon. On
Illuminations, the synthesizer was employed to create treated electronic sound, particularly of Sainte-Marie's voice. The opening track "God is Alive, Magic is Afoot" featured lyrics by
Leonard Cohen.
Peter Schickele provided arrangements to "Mary", "Adam" and "The Angel", whilst the four tracks "Suffer the Little Children", "With You, Honey", "Guess Who I Saw in Paris" and "He's a Keeper of the Fire" were Saint-Marie's first work not to be produced by Vanguard boss Maynard Solomon. Instead, they had a stripped-down rock sound and were produced by little known
folk-jazz songwriter Mark Roth. Bob Bozina played guitar, John Craviotta drums and percussion, and Rick Oxendine played bass. ==Reception==
