The majority of the album is based on tracks which were previously featured on Peste Noire demos (all written and recorded by La sale Famine de Valfunde on his own equipment).

Famine also used a lot of samples in his music – taken from a variety of sources – in order to construct the twisted, mysterious atmosphere that the final product holds.

According to Famine, the overall themes running through La Sanie des siècles are "a parallel between mediaeval and modern apocalypse; the decline of the current world and the desire to see it die out since it cannot be saved; vengeance and the fantasized return of our Own (our Own: a fallen nobility socially, psychically and physiologically humiliated).

A limited vinyl version co-produced by De profundis éditions and Finnish label Ahdistuksen Aihio Productions was released in August 2009.
