Crossing Borders – Exile, Identity, Spirituality
Alter Ratio presents the program highlighting three composers born in 1935: Leonid Hrabovskyi, Giya Kancheli, and Arvo Pärt.

These pieces will be performed at the festival in Bonn (Germany) in cooperation with In-Situ Art Society e.V.

Lux Aeterna. REVOICE
The Ukrainian vocal ensemble Alter Ratio is causing an international sensation. The twelve singers make their Dutch debut with Lux Aeterna Revoice. György Ligeti’s iconic Lux Aeterna — featured in Stanley Kubrick’s 2001: A Space Odyssey — is performed alongside four brand-new works dedicated to Ukrainian artists who lost their lives in the war.
This impressive and innovative programme sees each composer intertwine the singers’ voices with electronic soundscapes in a unique and personal way. Ligeti’s sixteen-part masterpiece acquires a new, poignant resonance. The twelve singers of Alter Ratio are joined by four electronic layers — echoes of voices silenced by war.
Including panel discussion about the power of art in times of war with Floris Akkerman, Christian van der Kooy, Olga Korol van NL4UA and Alla Zagaykevych
PROGRAMM
Gyorgy Ligeti “Lux aeterna”, for 16 voices (version for 12 voices and electronic)
Peter Kerkelov “phos-phorus”, for vocal ensemble and electronic
Maksym Kolomiiets “Disappearing voices”, for vocal ensemble and electronics on a text by Viktor Rekalo
Maxim Shalygin “Sub Rosa”, for vocal ensemble and electronics on a text by Robert Frost
Alla Zagaykevych “Psalms of Falling”, for vocal ensemble and electronics on a text by Iya Kiva
