Little Horse Deep is the moniker under which Eth Eonel records and releases "ambient" music, drones, etc. The name derives from the first song Eth Eonel ever wrote (as a four year old), called Lille Hest (Norwegian, meaning Little Horse). The first song Eth Eonel wrote in this genre was a drone made from timestretching a recording of Lille Hest, making it a 12 minute drone, which he called Little Horse Sleep.
