Stefano Musso studied art and electronics in his home town of Milan, Italy, and began performing ambient-electronic music under the name Alio Die in 1989. Characterized by evocative acoustic sounds manipulated and tendered electronically, Alio Die's work builds intimate soundscapes tied to the mystery and majesty of life and nature. His CD "Under an Holy Ritual", released on Projekt in 1992, was received with international acclaim. He subsequently released more than 20 CDs, and collaborated with many well-known artists such as Robert Rich, Vidna Obmana, Mathias Grassow, Nick Parkin, Yannick Dauby, Amelia Cuni, Raffaele Serra, Ora, Antonio Testa.
What makes his works glow is his attention to detail. There is always something changing -- maybe something in the background that came to the foreground slowly and got toyed with... maybe a very slow addition of a bagpipe instrument or stringed instrument. Despite how "repetitive" some of the actual "notes" or "samples" are, they never SEEM that way due to constant modulation, addition of atmospheric noise, and re-contextualization.
Apsaras is a godsend of an album. Loving classical Indian music, I'd longed to hear an Indian vocalist sing in an ambient context -- where the drone wasn't upheld solely by harmoniums or tampura, and where the approach wasn't the pompousness & tawdry love affairs of Bollywood. Not only is the vocalist's voice wonderful, but 6 different contexts of her voice with Alio Die as the backdrop.
Tempus Rei & Aura Seminalis were the first two I found that got me hooked. The feel of both these albums is very trans-chronological. Both albums develop, without any specific direction. Aura Seminalis has a historical religious feel -- a basis in Gregorian-style chants, but not in an obvious or domineering way. Tempus Rei has a supernatural orchestral feel, with an odd sense of time -- as if two string trios are in a cave playing some piece of short music slowly; one trio playing it normally, the other playing it in reverse.
Eleusian Lullaby is another great album with a kind of polyphonic feel. There is much in the way of natural, organic instrumentation here, where much of the ambience is derived from delay, echo, sustain. Femme vocals are beautifully done; there are some gongs/bells, some strings (dulcimer & harp?), and mbira. Plenty of atmosphere here as well; sometimes the vocals are the vocals, sometimes just one aspect of the sonic tapestry.
Any of his works I can recommend to audiophiles. Even if you're new to this type of music, I think one can have an enjoyable experience with Alio Die's works. Give the sound your sole attention, and hold no expectations for it to go anywhere or do anything. Let it take you where it will.
