Two music videos were made to promote Émilie Simon, for the songs "Désert" and "Flowers".

In April 2007 Émilie released her second recording in the United States, The March of the Empress, and a third, The Big Machine, in 2011.

Coincidentally, in the midst of her search for sounds for the album, she was contacted by producer Luc Jacquet to compose the original soundtrack for his documentary film La Marche de l'empereur (March of the Penguins in English), concerning the annual migration of emperor penguins.

The version of March of the Penguins that was released in the United States and in English Canada used a more traditional documentary soundtrack scored by Alex Wurman, as the local producers feared that the Simon soundtrack would be too challenging for North American viewers[citation needed] (the only cinemas in North America to screen the film with the Simon soundtrack were those of the French circuit in the province of Quebec[citation needed]).

The sound remains nonetheless that of electronic music while her voice maintains its candor, softness, and beauty.

The album utilizes Opendisc technology which enables access to special content such as songs and music videos on her official website.

In late 2006, she released The Flower Book in the USA (April 2007 in Canada), a compilation album of her first three records, with some added material from her short international tour which included stops in New York and Los Angeles.

The track "Rose hybride de thé", originally from Végétal, is officially the first single release intended for US audiences.

The set exists as a sole CD or DVD, and contains live footage from a concert recorded on 19 September 2006.
