BULLITT, JOHN T : Earth Sound
Small edition recordings of the earth's interior, taken from digital seismographs located around the planet. Since the true frequencies are extremely low, they have to be sped up considerably to bring them into the range of human audibility. There are 3 tracks, the first, at 2450x acceleration, captures an unbroken month, the second, at 10,000 x , about 4.5 months and the last, at 245x, three days around the December 2004 tsunami. You mostly hear earthquakes - and there are a lot of them at varying amplitudes - as pops, cracks and roars set in a constant sussurus that is the ocean's waters moving. It's stereophonic because the earth is round and the seismographs are far apart. The booklet notes are excellent, full and highly informative, and include the 'scores', showing the extraordinary frequency of events. Triple gatefold digi-pack. For total immersion or ambiance. An essential soundscape document.
