Orpheus Brewing Company presents Chamber Cartel in a performance of Pléïades by Greek composer Iannis Xenakis. Written for six percussionists, Pléïades is a musical reanimation of the Seven Sisters of Greek literature in four movements: Peaux (“Skins”), Métaux (“Metal”), Claviers (“Keyboards”), and Mélanges (“Mixture”). In this work, Xenakis reanimates the Pléïades not as relics of Greek fable, but as “a human universe that is submerged in another musical dimension through pitch.” Used in this performance is an instrument called a sixxen, nineteen metal bars tuned microtonally and played simultaneously, built by Chamber Cartel's Caleb Herron. Its name is a blending of “six" (the number of performers required), and "xen" (after Xenakis). Performing Pléïades in this concert are Atlanta’s Caleb Herron, Paul Stevens, and Victor Pons, Denver’s Christopher Eagles, San Diego's Sean Dowgray, and Morris Palter, Artistic Director of the University of Alaska’s Ensemble 64.8.
