Ambienti Coassiali began in the '80s as a parallel project of Capricorni Pneumatici, in Milan and surrounding areas.

Ambienti Coassiali's debut release, simply titled Vol. 1, was self-released as an incredibly limited cassette in 1988. The compositions were recorded solely with a Yamaha DX7 and two track Revox A77 tape machine, creating straight-to-tape minimalist ethereal FM synthesis compositions. Both the name of the project and the title of the pieces, numbered 1 to 6 corresponding to as many rooms (stanze), recall the concept of ambient music that underlies Vol. 1 - it is music that gradually reveals itself in its surreal development, and aims especially at the subconscious of those who do not listen carefully.

Parallel to the musical project Ambienti Coassiali, a video project has developed - not by chance called "Empty Heads" - which is based upon the same concepts. Originally prepared as ambient "video wallpaper", the video project incorporates synthetic images generated with analog electronic television equipment. Empty Heads participated in video festivals around the world in the late 1980s and the project has evolved over the last 30 years, realizing the finished Ambienti Coassiali Vol. 1 visual project in 2017.

With the release of 2017's Spare Rooms on Italy's legendary Artisti Del 900 (ADN) label, Incidental Music's 2018 vinyl re-issue of Vol. 1, and the forthcoming Vol. 2, Ambienti Coassiali continues to surprise with new compositions nearly 30 years later.
