Ulan Bator is a French experimental post-rock band founded in 1993 by Amaury Cambuzat and Olivier Manchion.

The first meeting of Zappi W. Diermaier, Jean-Hervé Péron (of Faust), Olivier Manchion and Amaury Cambuzat (of Ulan Bator) was recently released as Collectif Metz/Faust.

They decided to invite Franck Lantignac for a special Ulan Bator reunion featuring the original line-up for the Avant Garde Festival.

Then in late Spring 2006 Cambuzat and Manchion toured as Cargo Culte, also known as the Ulan Bator Duo.

Cambuzat revived the group in 2013 with a completely different line-up for a tour of the US and a new CD and DVD entitled "En France/En Transe".

The new line-up included Cambuzat's previous bandmate Diego Vinciarelli from Chaos Physique and Ondes Martenot player Nathalie Forget.
