For the last batch of our Iannis Xenakis retrospective, we have remastered important recordings from the late 60s that had never been re-issued since their original LP version. The works here conducted by Marius Constant include the Polytope de Montréal, composed for an installation Xenakis made in the French pavilion of the 1967 World Fair, including a sensational light show. It has never been recorded otherwise! Also included are the ballet Kraanerg, number-theory-inspired Syrmos, and mythological works Medea (also an absolute premiere) and Oresteia (probably his stage masterpiece).

Sometimes controversial, always original, Iannis Xenakis (1922-2001) was one of the leading lights in the world of contemporary music.
This is a world premiere recording of Xenakis’s music for keyboard instruments composed for computer. Unplayable by human hands!

After “La Légende d’Eer” in 2016, the PERIHEL series presents one of the milestones of electroacoustic music: IANNIS XENAKIS’ mindblowing 54-minutes oeuvre “Persepolis”, mixed from the original 8 track tapes by MARTIN WURMNEST and mastered / cut by RASHAD BECKER.
“Persepolis” is the longest electroacoustic composition by IANNIS XENAKIS (1922-2001) who ranks among the most influential 20th century avantgarde composers. Commissioned by the Persian Shah, the piece was part of a multimedia performance – XENAKIS’ so-called “polytopes” – which premiered in 1971 in Shiraz-Persepolis (Iran) as a performance including light-tracks, laser beams, groups of children walking around with torches and 59 loudspeakers to project the music in an open-air situation. XENAKIS had realized “Persepolis” on 8-track analogue tape in the Studio Acusti in Paris and released a stereo reduction on vinyl in the famous Philips series “Prospective 21e Siècle” in 1972, adding the new subtitle “We bear the light of the earth”, his most hymnal title ever.
Out of print for decades now, the LP became – especially the Japanese edition from 1974 – one of the most expensive collector’s item of electroacoustic music. There were some later CD versions with different durations – too long due to a wrong sample rate, others shortened by 3 minutes due to other reasons. The PERIHEL series now presents a new version: mixed from the original (!) master 8 track tapes by longtime zeitkratzer sound engineer MARTIN WURMNEST and mastered by RASHAD BECKER at D&M, Berlin – the same experts who had already taken care of the 2016 KARLRECORDS release of “La Légende d’Eer”, another milestone composition among the works of the Greek-French avant-garde composer.

This album is our second collection of Iannis Xenakis’ music recorded under the aegis of Konstantin Simonovitch. It includes Atrées and Morsima-Amorsima (“what comes by fate-what doesn’t”), two works composed using probability theory, as well as notable chamber and solo pieces such as ST/4 for string quartet. Featuring the young Georges Pludermacher in one of his earliest recordings!
