Iannis Xenakis compostion Diamorphoses
for 2-track tape & at least 4 loudspeakers.
Taken from the Adventures In Sound compilation on EL Records.
The sound-world Xenakis designed for this work combines the violent noises of jet engines, trains, and an earthquake with high bell-like sounds. The contrasting character of these sonic layers interacts with shifting densities and successions of events to produce a complex, yet balanced form. The equilibrium of high, sharply defined sounds and low, continuous ones is made manifest in the overall architecture; the outer passages are dominated by the roaring, sustained sounds framing a central section of more discontinuous, shifting textures of bells and many other sonorities.
