ISOTROPES - Collegium Vocale

unique collaboration between BL!NDMAN and Collegium Vocale Ghent

16 voices and 4 saxophones are united in one spiritual programme in which old and new compositions come together. The amplification and positioning of choir and instruments enhances the audience’s feeling of being amidst the sounds. Isotropes is a unique experience that adds a rich intensity to these musing pieces.

“Uniformity in all directions” is the scientific meaning of isotropy, a term often used in mathematics, physics and biology. In Isotropes, these particles that remain equal when moving around in different directions are used as a metaphor for the sounds that surround and fuse with the audience. Electronics are being used to merge the 16 voices and the 4 saxophones.
With compositions of Jonathan Harvey, Eric Sleichim, Matheus de Sancto Johanne, and Petrus Abaelardus we hear a surprising mixture of contemporary and early music. Breath, the origin of the earliest music, establishes the link between both.
Eric Sleichim based his Isotropes de l’ombre on a text by Leonardo Da Vinci that describes how the fading of a sound of a clock is a phenomenon that takes place almost entirely in the ear itself. The constant interaction between the saxophones and the choir breathes contemplation in both the literal and figurative sense.

“La force de Sleichim est, notamment, sa capacité à embarquer l ‘écoute dans la pure jouissance sonore, surgie des séductions du saxophone pour se transformer, grâce à l’électronique et au jeu des enceintes, en un monde exclusif, puissant, infini.
Tous les musiciens sont unis par une virtuosité qui trouvera son sommet dans ‘Isotropes’, glorieux avatar de l’Ars Subtillor du XIIIe siècle. On en redemande.”
