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.
