Ulan Bator was founded in 1995 by Amaury Cambuzat and Olivier Manchion. Near Paris, they discovered an abandoned chalk mine, which they decided to use as a rehearsal space and recording studio. They recorded and produced their first three albums (Ulan Bator, 2°, Végétale) for Les Disques du Soleil et de l’Acier in this space. Several days before starting the recording of the first album, they decided to add a drummer to the band, so drummer Franck Lantignac joined the band from 1995 to 1998, performing at festivlas like Transmusicales de Rennes, Roskilde, Musique Action.

HELIOGABALE is a Paris band whose road met Steve Albini's, Al Sutton's or Iain Burgess'. This time they stopped by the doorstep of French sound engineers Patrick Müller and Antoine Gaillet who respectively recorded and mixed down the band's sixth album to be released in September 2010. Since its beginning in 1992 HELIOGABALE has been using change and evolution as keywords of its music; each album was a break with the previous one, highlighting a unique style. This new opus contains ten songs, dressed up in shadows and lights : some sort of an inventory, polaroid cuts from lives where gymnopedical melodies intervene in the band's rhythmical universe.
