From the opening deep rumblings of this disc, it is immediately 
                clear that this is something unusual. Comprising six works for 
                hyperbass flute and tape, the environmental concern is obvious 
                from the title. Each work concerns a glacier that still exists, 
                using sound to describe the life-force of nature which is inherent 
                in these landscapes. 
                The 
                  instruments used are quite extraordinary. The hyperbass flute, 
                  an invention of the performer and composer Robert Fabbriciani, 
                  is the largest and lowest member of the flute family. Combined 
                  with a tape part of natural sounds and pre-recorded hyperbass 
                  flute, these compositions are soundscapes which are full of 
                  imagery and suggestion - the first track even made me start 
                  shivering! The sounds really are incredible, and I felt an urge 
                  to take the disc to a recording studio to hear the low sounds 
                  through speakers of a higher quality than my home stereo in 
                  order to get the full effect. 
                Although 
                  the tracks appear quite long when seen in a listing, the eleven 
                  and a half minutes of the first track, Glacier Ururashraju 
                  passed by quickly, and I could have heard much more. I initially 
                  wondered whether there would be enough scope in the musical 
                  material to sustain a whole disc, but Pasterze offers 
                  contrast with accents and rhythmic impetus, alongside greater 
                  air sounds and a general sense of a colder, wilder place. Bird 
                  sounds can be heard in the background and pizzicato tongue rams 
                  give an occasional bass line. The music builds gradually to 
                  a dramatic crescendo of breath sounds. Despite inhabiting the 
                  same soundworlds, the rest of the tracks also offer variety, 
                  each having its own sense of identity. There are some musical 
                  ideas which make regular appearances; these give some overall 
                  sense of structure and do not become tedious. Track six, Chalcaltaya 
                  Glacier is faster paced, containing some highly alluring 
                  multiphonic sounds. The shortest of the works, its dramatic 
                  opening is utterly absorbing and gives way to atmospheric stillness. 
                Fabbriciani’s 
                  playing is imaginative, and makes use of various contemporary 
                  techniques to create a wide palette of sounds, including harmonics 
                  and air sounds. I was captivated with this unique music from 
                  beginning to end. There is a sense of gradual evolution, as 
                  if seeing these landscapes from the air. This music appeals 
                  to the senses and conjures up images of the places it represents. 
                  In a time of climate change and environmental campaigning, this 
                  is probably one of the very best arguments I have heard to do 
                  what we can to stop global warming.
