Ichthyology [ich·thy·ol·o·gy] noun The branch of zoology that studies fishes: their physiology, history, economic importance, etc.First reissue of Ittiologia, the second of Intervallo's seven reissues of the amazing nature-themed series of library LPs released in the first half of the '70s by Cardium, Chic, Nereide, Musical, Rhombus, Spring, and Weekend labels. These are seven albums that have never been reissued until now -- real collectors' items that have acquired a minor cult status in the decades since they first appeared. Ittiologia, released in 1973 on Cardium, features music by composers Alessandro Alessandroni, Amedeo Tommasi (both under his given name and his Atmo alias), and Franco Tamponi, and is a rare and delicate experiment in the art of balancing experimental music and classic Italian library music of the '70s. The underwater and liquid atmosphere of each track was conceived to bring to call to mind "romantic algae," "threats on the sea bottom," "deep water," and "abyssal mountains" (to paraphrase translations of some of the track titles on this small masterpiece -- "Alghe Romantiche," "Minaccia sul Fondo," "Acque Profonde," and "Fascia Abissale"). Some compositions appear in two alternate versions (with small variations, different orchestrations, and additions), showing that the three musicians were always looking for new ways to express themselves; each track was a work in progress, part of never-ending research. With its perfect equilibrium between experimental and classical atmospheres,Ittilogia is a complex portrait of a fragile and always changing ecosystem.
