He then began, in early 2000, to record under the pseudonym "doss-house". Fascinated by the oneiric world, Alex seeks to recreate the musically naivete of childhood, and the madness of dreams. His music is mainly influenced by electronica/IDM, and such names as Plaid, Aphex Twin and Kettel.

He released his first album Dreamland, with a mixture of original compositions, and a few remixes. In parallel, he is working with the writer Sebastian Bellanger on the soundtrack of his novel Lunerf and of his book Lacryma. Following Dreamland, came an EP on the Dedpop label in 2008.

Subsequently, his encounters with fellow electronica artists Ritzen and John Merick, give birth to the project Aniline, and the trio Meriline Avenue.

Alex then joined the Bee Records label in 2012.
