Boris Billier is a french musician based in the Pyrenees mountains in southern France. He started to compose with environmental sound recordings in 2002. He toured with different solo projects, playing "acousmatic" concerts. He often collaborated with contemporary theatre.
From 2013, he started to focus on instrumental music, with a particular interest for piano, and to share tracks under Aries Mond pseudonym.
His first release, "Come On Let's Wait" came from his land, where, Indian Summer 2016 turned into an endless Autumn lasting the whole Winter of 2017. Before time definitively stops, he decided to record a few piano takes again.
