Now available separately, this is disc IV ('Les Polytopes III') of the 5LP/5CD box set 'Electroacoustic Works' that celebrates the 100th anniversary of Iannis Xenakis (on May 29th, 2022), one of the most influential 20th century avantgarde composers. All tracks have been newly mixed by longtime Zeitkratzer sound engineer Martin Wurmnest and mastered by Rashad Becker and finally reveal their full sonic range and dynamics.
