Limited 180gm pink colored vinyl LP pressing. A Posteriori is the sixth studio album by German musical project Enigma. In December 2006, the album was nominated in the Best New Age Album category in the 2007 Grammy Awards. While the previous album, Voyageur, contained minimal amounts of the project's signature sounds, A posteriori only contains the signature "Enigma horn" (a foghorn) during the opening minute of the album, and even then it is a fleeting glimpse. Coupled with the album's subject matter of the collision of the Milky Way and Andromeda galaxies, A posterioriis, compared to earlier releases, stark and foreboding.
