At the end of the '60s in Italy - but also abroad, especially in France and England - a very particular trend began to spread, that one known as 'Library music' or 'sonorization': as suggested by its name, those were real music libraries intended for the accompaniment of audiovisual productions such as

television programs, advertisements, documentaries and films. Since they were created in total artistic freedom condition, they are often difficult if not impossible to catalog, as they're not anchored to a specific musical genre; this freedom also allowed the authors to compose, sometimes in the most complete anonymity, experimental and avant-garde music, capable of anticipating the sounds that only many years later would have been widespread on a larger scale.

Egisto Macchi (1928-1992) was one of the most active composers of the sonorization and soundtrack genres together with artists such as Piero Umiliani, Alessandro Alessandroni and Ennio Morricone; he also collaborated with the latter in the experimental music project Gruppo di Improvvisazione Nuova Consonanza. "Fauna Marina" is among his most popular and sought-after by collectors titles: a set of eleven compositions intended to accompany the images of a hypothetical fish fauna documentary, an abstract hybrid of classical, contemporary and jazz music that is still fresh and surprising today.

"Fauna Marina" is part of a reissues series, made in collaboration with Edizioni Leonardi (Milan, Italy), of extremely rare library music LP's published between late '60s and early '70s, most of which have never been released again until today, and that are finally made available again for

collectors and sonorization music lovers.
