Monade is a Bordeaux, France-based post-rock band which was initially a side project of Lætitia Sadier, a founding member of Stereolab.
The name "Monade" was taken from Cornelius Castoriadis' concept of the "monade psychique" (psychical monad), which was the term Castoriadis used to describe the undifferentiated infantile psyche, before its shattering into the ego, super-ego, and id through the process of socialization. Lætitia Sadier has stated that the name has a double meaning – the word "monade" is from the root word "mono-" (meaning "one") and etymologically related to the sound recording term "mono", which stands in contrast to stereo, and therefore is a reference to Monade as a solo side project to Stereolab.[2] The title of Monade's first album pays tribute to a libertarian Marxist political group founded by Castoriadis, Socialisme ou Barbarie.
